Description

Technical Field

[0001] The present application relates to the field of image processing technology, and in particular to a countdown reminder method, a countdown reminder device, a computer-readable storage medium, and an electronic device. Background Art

[0002] In some software usage scenarios, countdowns will appear. For example, before a battle game starts, the character controlled by the player will be in a virtual waiting area, and the interface will display a countdown before the game officially starts. After the countdown ends, the game officially starts. For another example, the product interface of an e-commerce platform will display a countdown for grabbing coupons and a countdown for sales.

[0003] Through research, we found that most users will temporarily exit the software and use other applications first, and then enter the software to check the countdown after a while. However, some users will forget to enter the software to check the countdown, or, due to incorrect estimation of the time, they will find that the countdown has already ended after entering the software, which will lead to the loss of some opportunities (such as the time to start the game, the time to revive the game character, the time to shop, etc.).

[0004] Therefore, it can be seen that the countdown reminder after exiting the countdown interface is particularly important for users, and the relevant technology usually requires a lot of time cost for countdown reminder. Therefore, how to realize the countdown reminder after exiting the countdown interface while saving time cost, so that users can understand the countdown related to the countdown interface when the countdown interface is not displayed, has become a problem that needs to be solved urgently.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute relevant technology known to ordinary technicians in the field. Summary of the invention

[0006] The purpose of the present application is to provide a countdown reminder method, a countdown reminder device, a computer-readable storage medium and an electronic device, which can promptly obtain a current screenshot corresponding to a specific interface when a switching operation from a specific interface to a current interface is detected, and a number set and countdown-related text are identified from the current screenshot, and a target number matching the countdown-related text is determined from the number set, and then a countdown reminder is performed for the target number in the current interface, and a high countdown acquisition success rate can be guaranteed without paying additional time costs. What can be achieved is a countdown reminder after exiting a specific interface containing a countdown, so that the user can also understand the countdown related to the specific interface when the specific interface is not displayed.

[0037] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as being limited to the examples set forth herein; on the contrary, these embodiments are provided so that the present application will be more comprehensive and complete, and the concept of the example embodiments will be fully conveyed to those skilled in the art. The described features, structures, or characteristics may be combined in one or more embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present application. However, those skilled in the art will appreciate that the technical solutions of the present application may be practiced while omitting one or more of the specific details, or other methods, components, devices, steps, etc. may be adopted. In other cases, known technical solutions are not shown or described in detail to avoid obscuring various aspects of the present application.

[0038] See also Figure 1 , Figure 1 The flowchart of the countdown reminder method according to one embodiment of the present application is schematically shown. Figure 1 As shown, the method includes the following steps.

[0039] Step S110: when a switching operation for a specific interface is detected, a current screenshot corresponding to the specific interface is obtained.

[0040] Step S120: Identify the number set and countdown related text in the current screenshot.

[0041] Step S130: Determine a target number that matches the countdown-related text from the number set.

[0042] Step S140: In the current interface, a countdown reminder is given for the target number.

[0043] Implementation Figure 1 The method shown, when detecting a switching operation from a specific interface to a current interface, promptly acquires the current screenshot corresponding to the specific interface, identifies a number set and countdown-related text from the current screenshot, and determines the target number that matches the countdown-related text from the number set, and then in the current interface, performs a countdown reminder for the target number, and can ensure a high countdown acquisition success rate without paying additional time costs, and can achieve a countdown reminder after exiting a specific interface containing a countdown, so that the user can also understand the countdown related to the specific interface when the specific interface is not displayed. In addition, since the present application acquires the current screenshot corresponding to a specific interface, a more comprehensive number set can be acquired, and the target number that matches the countdown-related text can be accurately determined from the number set, and the target number will not be misjudged due to only partially acquiring the interface. Based on this, the number accuracy of the countdown reminder for the user is higher.

[0044] Next, the above steps of this exemplary embodiment are described in more detail.

[0045] In the related art, a countdown acquisition function is developed for software. After the countdown display coordinates of the software are acquired, the countdown can be directly acquired according to the coordinates every time the user exits the interface containing the countdown, and the countdown can be displayed to the user in other interfaces that the user is using.

[0046] However, the software version will be continuously updated, and the display coordinates of the countdown may change with the version update. This requires developers to pay attention to the version update of each software at any time and update the old display coordinates in time, otherwise the countdown cannot be obtained using the old display coordinates. Therefore, it can be seen that the relevant technology needs to pay a higher time cost, otherwise there will be a problem of low success rate of countdown acquisition. In order to solve the technical problems existing in the relevant technology, the present application discloses steps S110 to S140 to achieve efficient countdown acquisition and countdown reminder without paying additional time cost.

[0047] In step S110, when a switching operation for a specific interface is detected, a current screenshot corresponding to the specific interface is obtained.

[0048] Specifically, a specific interface (such as a game interface, an e-commerce interface, etc.) may be an interface corresponding to an application in a preset application set, wherein the application in the preset application set includes a countdown interface, and the specific interface may be understood as an interface including a countdown. The current interface may be any other interface other than the specific interface (such as a terminal device main interface, other software interfaces, etc.). In addition, optionally, if the current interface also includes a countdown, steps S110 to S140 and the solutions defined in the embodiments may be executed for the current interface.

[0049] In addition, the switching operation can be a single trigger operation (such as a gesture control operation, etc.) or a continuous operation (such as swiping up to call out the background and clicking the background corresponding to the current interface), etc., and the embodiments of the present application are not limited.

[0050] In order to be able to know the countdown progress in real time when the user exits a specific interface, you can first obtain the current screenshot corresponding to the specific interface when a switch operation for the specific interface is detected. For details, please refer to Figure 2 The current screenshot in 200.

[0051] In step S120, the number set and countdown related text in the current screenshot are identified.

[0052] Specifically, the numbers included in the number set may be all the numbers displayed in the current screenshot (eg, any number from 0 to 9). Figure 2 , Figure 2 The numbers and countdown-related texts are framed in the middle. It can be seen that the number set in the current screenshot 200 can be represented as {1, 8, 1, 5, 7, 3, 1, 1, 1, 5, 2, 0, 1, 2, 3}. The countdown-related text can be represented as "View Death Replay". Among them, the method of identifying the countdown-related text in the current screenshot is to extract the text information in the current screenshot, determine the preset text of the application corresponding to the specific interface (such as the preset text "View Death Replay" corresponding to application A), and then compare the text information with the preset text to determine the countdown-related text from the text information.

[0053] As an optional embodiment, identifying the number set and countdown-related text in the current screenshot includes: determining the cropping rule of the application corresponding to the specific interface; cropping the target area from the current screenshot based on the cropping rule; and identifying the number set and countdown-related text in the target area. This can narrow the recognition range, reduce the memory capacity occupied by the current screenshot, and exclude the numbers appearing in the target area to improve the recognition efficiency of the number set and countdown-related text.

[0054] Specifically, different applications may correspond to different cropping rules. For example, the countdown-related text of application A (e.g., "Start the game after the countdown ends") is displayed in the upper left corner, while the countdown-related text of application B is displayed in the upper right corner. Based on this, if the specific interface corresponds to application A, the cropping rule corresponding to application A for cropping the specified range in the upper left corner is read; if the specific interface corresponds to application B, the cropping rule corresponding to application B for cropping the specified range in the upper right corner is read. For example, the cropping rule may indicate that the specific interface is divided into four parts, obtaining an upper left area, a lower left area, an upper right area, and a lower right area of ​​equal size; wherein the range defined by the upper left area is the above-mentioned specified range in the upper left corner.

[0055] Among them, the cropping rules are used to limit the cropping range, cropping position, etc. of the current screenshot, which are not limited in the embodiments of the present application. After determining the cropping rules of the application corresponding to the specific interface, the target area can be cropped from the current screenshot based on the cropping rules; wherein the size of the target area is less than or equal to the size of the current screenshot, and the position and size of the target area depend on the cropping rules. Furthermore, the set of numbers and countdown-related text in the target area can be identified.

[0056] As an optional embodiment, recognizing the number set and countdown-related text in the current screenshot includes: training an object detection model based on the countdown interface corresponding to different applications; and recognizing the number set and countdown-related text in the current screenshot through the object detection model. In this way, accurate number recognition and accurate text recognition for different pictures can be achieved.

[0057] Specifically, for different applications, their countdown interfaces are usually different. For example, for application A, the countdown reminder position in its countdown interface is in the center of the screen, and for application B, the countdown reminder position in its countdown interface is in the lower right corner of the screen. Therefore, an object detection model can be trained based on the countdown interfaces corresponding to different applications, so that the object detection model can be used to detect the standby time values ​​and countdown-related texts in different countdown interfaces. Among them, the object detection model can be set to any desired structure and any parameters (such as downsampling 8 times parameters, downsampling 16 times parameters, etc.). For example, the object detection model can be set to a lightweight detection model YOLO-V5, etc., which is not limited in the embodiments of the present application.

[0058] For example, object detection models can be used to identify Figure 2 The number set in the current screenshot shown is {1, 8, 1, 5, 7, 3, 1, 1, 1, 5, 2, 0, 1, 2, 3} and the countdown related text "View Death Replay" to get the following Figure 3 The recognition results shown in Figure 3 In the current screenshot 300 shown, countdown related text can be marked by a text box, and each number in the number set can be marked by a number box; wherein both the text box and the number box can be referred to as a detection box, which is used to contain numbers / text.

[0059] In step S130, a target number matching the countdown-related text is determined from the number set.

[0060] Specifically, the number set includes redundant numbers, so the countdown value can be accurately located by determining the target number that matches the countdown-related text. In addition, optionally, the current screenshot may contain multiple countdown-related texts. If there are multiple countdown-related texts, there are target numbers that match each countdown-related text. Among them, for each pair of [countdown-related text, target number], the scheme of the embodiment of the present application can be executed to obtain an accurate target number as a countdown, and then, if there are multiple countdown-related texts, in the current interface, multiple countdowns can also be reminded separately. In addition, optionally, it also includes: in response to a hide operation / delete operation for a target countdown reminder, the target countdown in multiple countdowns can be hidden / deleted.

[0061] As an optional embodiment, determining the target number matching the countdown-related text from the number set includes: processing the number set based on a preset screening condition to obtain a target number set; wherein the preset screening condition includes at least one of the following: confidence, overlap, number display distance, number display size, and a predetermined screening area range; and determining the target number matching the countdown-related text from the target number set. In this way, the number redundancy in the number set can be reduced to obtain the target number set, and determining the target number matching the countdown-related text from the target number set can improve the positioning accuracy of the target number, and can improve the efficiency of determining the target number.

[0062] Specifically, the preset screening conditions may also include but are not limited to digital colors, etc., which are not limited in the embodiments of the present application. The means for processing the digital set based on the preset screening conditions include: fusion processing, screening processing, etc. In addition, the number of digits in the target digital set is less than or equal to the number of digits in the digital set.

[0063] As an optional embodiment, if the preset screening condition includes confidence, the number set is processed based on the preset screening condition to obtain the target number set, including: calculating the confidence of the number box used to display each number in the number set; based on the preset confidence range and the confidence of each number box, the numbers in the number set are screened to obtain the target number set. In this way, low-confidence numbers in the number set can be removed, and the redundancy of invalid numbers in the number set can be reduced, so as to improve the accuracy of subsequent determination of the target number.

[0064] Specifically, the confidence of the number box used to display each number in the number set is calculated, including: for the number box used to display each number in the number set, a confidence calculation formula is determined according to requirements (for example, the closer the number is to the center of the screen, the more likely it is to be a countdown, the closer the number is to the top edge of the screen, the more likely it is to be a countdown, etc.), and the confidence of each number box is calculated based on the confidence calculation formula as the confidence of the corresponding number; wherein, the higher the confidence, the more likely it is a countdown number.

[0065] Furthermore, based on a preset confidence range (e.g., 10 to 100) and the confidence of each number box, the numbers in the number set are screened to obtain a target number set, including: filtering out the confidences that do not fall within the preset confidence range to obtain a target confidence, and determining the numbers corresponding to the target confidences as the numbers in the target number set.

[0066] As an optional embodiment, if the preset screening condition includes the degree of overlap, the number set is processed based on the preset screening condition to obtain the target number set, including: for the numbers in the number set with overlapping display of number boxes, non-maximum suppression is performed to obtain the target number set. In this way, the redundancy of invalid numbers in the number set can be reduced to improve the accuracy of subsequent determination of the target number.

[0067] Specifically, the overlapping number frames in the number set are deduplicated by non-maximum suppression (NMS) to avoid one number corresponding to multiple number frames, thereby obtaining the target number set; wherein non-maximum suppression is used to search for local maxima and suppress the remaining values ​​in the neighborhood.

[0068] As an optional embodiment, if the preset screening condition includes the digital display distance, the digital set is processed based on the preset screening condition to obtain the target digital set, including: determining the digital frame center distance between every two numbers in the digital set; projecting the digital frame to which each number in the digital set belongs in a preset direction to obtain a projection result; determining digital pairs with intersections in the projection results and digital frame center distances less than the preset distance; merging each digital pair in the digital set to obtain the target digital set. In this way, the amount of data in the digital set can be reduced to improve the efficiency of determining the target number.

[0069] Specifically, the digital box to which each number in the digital set belongs is projected in a preset direction (such as the y-axis direction, the x-axis direction, etc.) to obtain a projection result, including: projecting the digital box to which each number in the digital set belongs in the preset direction to obtain a line segment corresponding to each digital box as a projection result.

[0070] Furthermore, determining that there is an intersection in the projection results and a digital pair whose center distance of the digital frames is less than a preset distance includes: determining the line segments with the intersection from the projection results to obtain multiple line segment sets, each line segment set contains at least two line segments, and the line segments in the line segment set have an intersection with at least one other line segment in the set; further, the digital frames corresponding to the line segments in each line segment set can be detected to determine the digital pair whose center distance of the digital frames is less than the preset distance; if the center distance of the digital frames of every two line segments in the line segment set is less than the preset distance, the numbers in the line segment set are determined as a digital pair; if there is a part of the line segments in the line segment set and the center distance of the digital frames between the two is less than the preset distance, the numbers corresponding to this part of the line segments are determined as a digital pair.

[0071] Then, the number pairs in the number set are merged to obtain a target number set, including: merging the number frames corresponding to the number pairs to obtain the target number set, wherein the numbers included in the target number set come from the merged number frames.

[0072] For example, through the above embodiment Figure 3 The number set {1, 8, 1, 5, 7, 3, 1, 1, 1, 5, 2, 0, 1, 2, 3} in the current screenshot shown in the figure is merged to obtain the following Figure 4 The results shown in Figure 4In the current screenshot 400, by determining the center distance of the number boxes between every two numbers in the number set, projecting the number boxes belonging to each number in the number set in a preset direction to obtain the projection results, and determining the number pairs whose projection results have intersections and whose center distances of the number boxes are less than a preset distance (e.g., 1 mm), the number pairs that can be determined are {1, 8}, {2, 0}, {1, 1}, {1, 5}, {1, 2, 3}, and then, the number pairs {1, 8}, {2, 0}, {1, 1}, {1, 5}, {1, 2, 3} can be merged to obtain the target number set {18, 1, 5, 7, 3, 11, 15, 20, 123}.

[0073] As an optional embodiment, if the preset screening condition includes a digital display size, the digital set is processed based on the preset screening condition to obtain a target digital set, including: determining a digital frame size corresponding to each digital in the digital set; and filtering out the digital frames that do not meet the preset size to obtain the target digital set. In this way, the digital that does not meet the preset size can be further filtered out to reduce the redundancy of invalid digital numbers in the digital set.

[0074] Specifically, in the number set, there may be some numbers whose number box sizes are too large or too small. For such numbers, the possibility that they belong to the countdown is 0. Based on the above embodiment, the number box size corresponding to each number in the number set can be determined; wherein the number box size depends on the number display size, and the larger the number display size, the larger the number box size; further, the numbers corresponding to the number box sizes that do not meet the preset size (e.g., length 10*width 10 to length 100*width 100) can be screened out to obtain the target number set.

[0075] For example, through the above embodiment Figure 4 The number set {18, 1, 5, 7, 3, 11, 15, 20, 123} in the current screenshot shown in the figure is screened based on the preset size, and the number {20} corresponding to the number box size that does not meet the preset size can be determined. Then, {20} can be screened out from {18, 1, 5, 7, 3, 11, 15, 20, 123} to obtain the following: Figure 5 The results shown in Figure 5 In the current screenshot 500, the number set includes {18, 1, 5, 7, 3, 11, 15, 123}.

[0076] As an optional embodiment, if the preset screening condition includes a predetermined screening area range, processing the number set based on the preset screening condition to obtain the target number set includes: obtaining the predetermined screening area range corresponding to the specific interface; filtering out the numbers in the number set that are outside the predetermined screening area range to obtain the target number set. In this way, numbers that do not meet the preset size can be further filtered out to reduce the redundancy of invalid numbers in the number set.

[0077] Specifically, the predetermined filtering area ranges corresponding to different application programs may be different. For a specific interface, its predetermined filtering area range may be determined to filter out numbers outside the predetermined filtering area range.

[0078] For example, through the above embodiment Figure 5 The number set {18, 1, 5, 7, 3, 11, 15, 123} in the current screenshot shown in the figure is screened based on the predetermined screening area range, and the numbers {11}, {15}, {18}, {123} outside the predetermined screening area range can be determined. Then, {11}, {15}, {18}, {123} can be screened out from {18, 1, 5, 7, 3, 11, 15, 123} to obtain the following: Figure 6 The results shown in Figure 5 In the current screenshot 600 , the number set includes {18, 1, 5, 7, 3} in the predetermined filtering area range 610 .

[0079] As an optional embodiment, if the predetermined screening area contains multiple numbers, it also includes: extracting the feature vector of each number in the predetermined screening area; calculating the similarity between each two feature vectors, and clustering each feature vector based on the similarity to obtain a cluster set; determining the target cluster with the least number of points in the cluster set; and filtering out the numbers corresponding to other clusters except the target cluster to obtain the numbers corresponding to the target cluster. In this way, numbers that do not meet the preset size can be further filtered out to reduce the redundancy of invalid numbers in the number set.

[0080] Specifically, for example, if the predetermined screening area contains multiple numbers, it is possible that the level values ​​corresponding to multiple game characters appear within the predetermined screening area, wherein the multiple game characters can be controlled by different players respectively. In view of the above situation, the feature vectors of each number in the predetermined screening area can be extracted, and the feature vectors can be used to describe the size, color, font, etc. of each number. Furthermore, the Euclidean distance / cosine distance between each two feature vectors can be calculated as the similarity, and each feature vector is clustered based on the similarity to obtain a cluster set. Determine the target cluster with the least number of points in the cluster set, and filter out the numbers corresponding to other clusters except the target cluster to obtain the numbers corresponding to the target cluster. Among them, if the number contained in the target cluster is 1, the unique number contained in the target cluster is determined as the target number, and if the number contained in the target cluster is 2, the number closest to the countdown related text is determined as the target number.

[0081] For example, through the above embodiment Figure 6 The number set {18, 1, 5, 7, 3} in the current screenshot shown is clustered based on the feature vector to obtain a cluster set, which includes: cluster {18} and cluster {1, 5, 7, 3}. Based on the above embodiment, the target cluster {18} with the least number of points in the cluster set can be determined, and the numbers {1, 5, 7, 3} corresponding to other clusters except the target cluster can be screened out, and then the following can be obtained: Figure 7 The results shown in Figure 7 In the current screenshot 700 shown, the number set includes the number {18}.

[0082] As an optional embodiment, determining the target number matching the countdown-related text from the target number set includes: determining the relative distance between each number in the target number set and the countdown-related text to obtain a relative distance set; and determining the number corresponding to the minimum relative distance in the relative distance set as the target number matching the countdown-related text. In this way, the target number set can be obtained based on the screening and merging of the number set, and the target number matching the countdown-related text can be selected from the target number set with a smaller data volume, thereby improving the efficiency of determining the target number.

[0083] Specifically, optionally, determining the relative distance between each number in the target number set and the countdown-related text to obtain a relative distance set includes: determining the first center position of each number in the target number set and the second center position of the countdown-related text; and then calculating the relative distance between each first center position and the second center position to obtain a relative distance set. Then, the number corresponding to the minimum relative distance in the relative distance set can be determined as the target number matching the countdown-related text.

[0084] Alternatively, determining the relative distance between each number in the target number set and the countdown-related text to obtain a relative distance set includes: determining the first center position of each number in the target number set and the central axis of the countdown-related text; and then calculating the relative distance between each first center position and the central axis to obtain a relative distance set. Then, the number corresponding to the minimum relative distance in the relative distance set can be determined as the target number matching the countdown-related text.

[0085] In step S140, a countdown reminder for the target number is performed in the current interface.

[0086] Specifically, in the current interface, a countdown reminder can be made starting from the number displayed as the target number. For example, if the target number is 5, a countdown starting from 5 is displayed, and the specific display content and display order can be 5->4->3->2->1->0. Among them, the current interface can be the first other interface that the user switches to from a specific interface (such as the main interface of the terminal device), or it can be the second other interface that is switched from the first other interface again (such as a social software interface), and so on. The current interface refers to any one of the non-specific interfaces that has been displayed. In addition, the method for countdown reminder of the target number can be: countdown reminder of the target number by voice prompt / text prompt / vibration prompt, etc.

[0087] As an optional embodiment, in the current interface, a countdown reminder for the target number is provided, including: displaying a countdown component in the current interface, and displaying a countdown reminder for the target number in the countdown component; or displaying a countdown icon in the current interface, and displaying a countdown reminder for the target number through the countdown icon. In this way, the user can also understand the countdown status in real time in other interfaces outside the specific interface, without setting a third-party interface for the application of the specific interface, thereby reducing development costs and maintenance costs.

[0088] Specifically, on the one hand, based on Figure 7 The set of numbers shown in {18} can be found in Figure 8 The current interface 800 (e.g., the main interface of the terminal device) shown in the figure displays a countdown component 810, in which a countdown reminder to "18" can be performed along with the clock element; wherein the countdown component 810 can be expressed in any form such as a pop-up window, a floating window, etc., and the countdown component 810 can be displayed in any position such as the top notification bar, the sidebar, etc., which is not limited in the embodiment of the present application. In addition, optionally, the countdown component 810 can also display countdown-related text at the same time. On the other hand, based on Figure 7 The set of numbers shown in {18} can be found in Fig. 9A countdown icon 910 is displayed in the current interface 900 (e.g., the main interface of the terminal device) shown. The countdown icon 910 can be directly represented by the countdown number 18, and the countdown reminder continues with the clock element; wherein, the representation form of the countdown icon 910 (e.g., shape, color, font, etc.) can be arbitrarily set based on actual needs, and the embodiments of the present application are not limited thereto.

[0089] As an optional embodiment, it also includes: when the target number countdown reminder reaches a specific value, a prompt message is output. In this way, the user can be reminded in time before the countdown ends, so that the user does not miss the opportunity corresponding to the specific interface (such as the game start time, the resurrection time, etc.).

[0090] Specifically, the specific value can be any value displayed during the countdown reminder process (such as 5, 3, etc.). When the target digital countdown reminder is a specific value, it is determined that the countdown is about to end. At this time, a prompt message is output to remind the user to switch back to the specific interface in time; among which, the prompt message may include but is not limited to: text messages, vibration messages, voice messages, etc.

[0095] Step S1016: Processing the digital set based on preset screening conditions to obtain a target digital set; wherein the preset screening conditions include at least one of the following: confidence, overlap, digital display distance, digital display size, and a predetermined screening area range.

[0096] Step S1018: Calculate the confidence of the number box used to display each number in the number set; based on the preset confidence range and the confidence of each number box, filter the numbers in the number set to obtain a first number set.

[0097] Step S1020: For the numbers in the first number set that have overlapping number frames, non-maximum suppression is performed to obtain a second number set.

[0098] Step S1022: determine the center distance of the digital frames between every two numbers in the second digital set, project the digital frames to which each number in the second digital set belongs in a preset direction to obtain a projection result, and then determine the digital pairs whose projection results have an intersection and whose center distance of the digital frames is less than a preset distance; merge each digital pair in the second digital set to obtain a third digital set.

[0099] Step S1024: determining the size of the number frame corresponding to each number in the third number set, and filtering out the numbers corresponding to the number frame sizes that do not meet the preset size, so as to obtain a fourth number set.

[0100] Step S1026: Obtain a predetermined filtering area range corresponding to a specific interface, and filter out the numbers outside the predetermined filtering area range in the fourth number set to obtain a target number set; wherein, if the predetermined filtering area range contains multiple numbers, it is also possible to extract the feature vectors of each number in the predetermined filtering area range, calculate the similarity between each two feature vectors, and cluster each feature vector based on the similarity to obtain a cluster set, and then determine the target cluster with the least number of points in the cluster set, filter out the numbers corresponding to other clusters except the target cluster, and obtain the numbers corresponding to the target cluster.

[0101] Step S1028: Determine the relative distance between each number in the target number set and the countdown-related text to obtain a relative distance set, and determine the number corresponding to the minimum relative distance in the relative distance set as the target number that matches the countdown-related text.

[0102] Step S1030: In the current interface, a countdown component is displayed, and a countdown reminder for the target number is displayed in the countdown component; or, in the current interface, a countdown icon is displayed, and a countdown reminder for the target number is displayed through the countdown icon.

[0103] Step S1032: When the target digital countdown reminder reaches a specific value, a reminder message is output.

[0104] It should be noted that steps S1010 to S1032 are Figure 1 The steps and their embodiments shown correspond to each other. For the specific implementation of steps S1010 to S1032, please refer to Figure 1 The steps and embodiments shown are not described in detail here.
