[0024] In order to enable ordinary persons in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings.

[0025] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein.

[0026] The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0027] According to one aspect of an embodiment of the present invention, a method for determining a page indicator parameter is provided. Optionally, as an optional implementation, the method for determining a page indicator parameter may be, but is not limited to, applied to: Figure 1 The system for determining page index parameters in the hardware environment shown in FIG. 1 may include, but is not limited to, a terminal device 102, a network 104, and a server 106. The terminal device 102 runs a target website (such as a target website) logged in with a target user account. Figure 1 The target website is shown as a browser, which includes a search control and related data). The terminal device 102 includes a human-computer interaction screen, a processor and a memory. The human-computer interaction screen is used to display the interface content in the target website (such as Figure 1 The processor is used to generate an interaction instruction in response to the above human-computer interaction operation and send the interaction instruction to the server. The memory is used to store the information in the above target website, as well as the page loading video obtained by screen recording and the image sequence obtained by sampling.

[0028] In addition, the server 106 includes a processing engine, and the processing engine is used to perform storage or reading operations on the database 108. For example, the database 108 stores the above-mentioned received image sequence and the page indicator parameters determined for the target page.

[0029] The specific process is as follows: In step S102, a page loading video is obtained in the terminal device 102, and the page loading video is a screen recording video obtained after the target website starts to load the target page. Then, steps S104-S106 are performed to sample the page loading video to obtain an image sequence. The image sequence is sent to the server 106 through the network 104.

[0030] After the server 106 stores the received image sequence in the database 108, step S108 is executed to sequentially obtain the image change rate between two adjacent images in the image sequence from the database. Then, as in step S110, the first screen loading time of the target page is determined based on the page loading time corresponding to each of the two adjacent target images.

[0031] In addition, the system for determining the above-mentioned page index parameters may also include but is not limited to the terminal device 102. That is to say, for a terminal device with strong processing capabilities, the following steps can be completed independently: as in step S202, a page loading video is obtained in the terminal device 102, and the page loading video is a recorded video obtained by screen recording after the target website starts to load the target page. Then execute step S204 to sample the above-mentioned page loading video to obtain an image sequence. As in step S206, the image change rate between two adjacent images in the image sequence is obtained from the database in sequence. Then as in step S208, based on the page loading time corresponding to each of the two adjacent target images, the first screen loading time of the target page is determined.

[0032] Above Figure 1-Figure 2 The interface and process steps shown are examples and are not limited in this embodiment.

[0033] It should be noted that, in this embodiment, after obtaining the page record video, the page loading video is sampled to obtain an image sequence. Then, the image change rate between two adjacent images in the image sequence is obtained in turn, and the first screen loading time of the target page is determined based on the page loading time corresponding to each of the two adjacent target images. In other words, based on the change rate of the page elements displayed during the loading process of the target page in the target website, the first screen time corresponding to the target page is determined without relying on the intrusion code, which reduces the operational threshold for determining the page indicator parameters, thereby achieving the effect of improving the parameter determination efficiency, thereby overcoming the problem of low determination efficiency in the method provided in the related art.

[0034] Optionally, in this embodiment, the terminal device may be a terminal device running the target website, and may include but is not limited to at least one of the following: a mobile phone (such as an Android phone, an iOS phone, etc.), a laptop, a tablet computer, a PDA, a MID (Mobile Internet Devices), a PAD, a desktop computer, a smart TV, etc. The network may include but is not limited to: a wired network, a wireless network, wherein the wired network includes: a local area network, a metropolitan area network and a wide area network, and the wireless network includes: Bluetooth, WIFI and other networks that implement wireless communication. The server may be a single server, or a server cluster consisting of multiple servers, or a cloud server. The above is only an example, and this embodiment does not impose any limitation on this.

[0035] Optionally, as an optional implementation, as Figure 3 As shown, the determination of the above page index parameters includes:

[0036] S302, obtaining a page loading video, wherein the page loading video is a recorded video obtained by screen recording after the target website starts to load the target page;

[0037] S304, sampling the page loading video to obtain an image sequence, wherein the image sequence includes a group of images arranged in an orderly manner;

[0038] S306, sequentially calculating the image change rate between two adjacent images in the image sequence until a target image change rate is obtained, wherein the image change rate is used to indicate the difference between the page elements respectively contained in the two adjacent images, and the target image change rate is the image change rate that has reached a convergence condition;

[0039] S308, determining the first screen loading time of the target page based on the page loading times corresponding to the two adjacent target images, wherein the two adjacent target images are images used to obtain the target image change rate.

[0040] Optionally, in this embodiment, the above-mentioned method for determining the page index parameter may be applied, but not limited to, to the process of loading a page on a target website, wherein the target website may be used, but not limited to, to display web pages under different links. For example, the target website here may be a browser, and different search result pages may be displayed and loaded by inputting search keywords. This is an example, and this embodiment does not make any limitation to this.

[0041] Optionally, the page elements in the target page to be loaded in the embodiment of the present application may include, but are not limited to: one or any combination of text elements, image elements, and video elements. The above page elements may also be presented in the target page in different ways, such as being inserted into the target page in the form of a plug-in, floating at any position of the target page in the form of a floating window, displayed in the header of the target page in the form of a banner, displayed in the sidebars on both sides of the target page in the form of a couplet, etc. The above are examples, and this embodiment does not make any limitation to this.

[0042] In addition, in this embodiment, the first screen time to be determined is an important indicator of website user experience, which refers to the time required for the target area in the page of a target website to be filled. When the page is fully opened, the total loading time is much longer than the first screen time. When the target area in the page is filled, the user will be allowed to operate the displayed content.

[0043] Optionally, in this embodiment, two adjacent images in the above image sequence can be as follows: Figure 4 As shown in FIG. 1 , the image sequence includes a group of N images obtained after the page loading video is collected. According to their playback order, two adjacent images are divided into a group, such as image 1 and image 2 are divided into image group G1, image 2 and image 3 are divided into image group G2, and so on, until image N-1 and image N are divided into image group G1. (N-1) .

[0044] Further, in this embodiment, the image change rate between the two images in each image group may be determined, including but not limited to, by the following methods: comparing the page elements in the second image with the page elements in the first image; and determining the image change rate based on the comparison result. The comparison method here may include but is not limited to: 1) comparing the number of displayed page elements in the two images to obtain a quantity difference value; 2) comparing the area of ​​the display area occupied by the displayed page elements in the two images to obtain an area difference value. The image change rate between the two images is calculated based on the above-mentioned quantity difference value or area difference value. The above-mentioned comparison methods are examples and are not limited to this in this embodiment.

[0045] Optionally, in this embodiment, after obtaining the image change rate between two adjacent images, the target image change rate can be determined, but not limited to, when multiple consecutive image change rates tend to be stable, and then the first screen loading time of the target page is determined based on the target image change rate. It should be noted that, as the page is loading, the elements in the page will experience a change from large changes to small changes, and finally tend to be stable. Therefore, in this embodiment, by comparing and analyzing the changes in page elements in the page, it is ensured that the first screen loading time is determined more accurately, without relying on the code, thereby reducing the difficulty of the determination operation.

[0046] Through the embodiments provided by the present application, after obtaining the page recording video, the page loading video is sampled to obtain an image sequence. Then, the image change rate between two adjacent images in the image sequence is obtained in turn, and the first screen loading time of the target page is determined based on the page loading time corresponding to each of the two adjacent target images. In other words, based on the change rate of the page elements displayed during the loading process of the target page in the target website, the first screen time corresponding to the target page is determined without relying on the intrusion code, which reduces the operational threshold for determining the first screen time, thereby achieving the effect of improving the parameter determination efficiency, thereby overcoming the problem of low determination efficiency in the method provided in the related art.

[0047] As an optional solution, sequentially calculating the image change rate between two adjacent images in the image sequence includes:

[0048] Sequentially obtain the adjacent first image and second image from the image sequence and perform the following operations:

[0049] S1, performing binarization processing on the first image and the second image respectively to obtain a first candidate image and a second candidate image;

[0050] S2, performing a closing operation on the first candidate image and the second candidate image to obtain a first target image and a second target image, wherein in the first target image, the page elements in the first image have been converted into regular graphic blocks, and in the second target image, the page elements in the second image have been converted into regular graphic blocks;

[0051] S3, comparing the first target image and the second target image to obtain an image change rate between the first image and the second image.

[0052] Optionally, the binarization process in this embodiment can be, but is not limited to, a method of image segmentation. It is to set the grayscale of pixels greater than a certain critical grayscale value as the grayscale maximum value, and the grayscale of pixels less than this value as the grayscale minimum value, thereby achieving binarization. For example, the black and white binarization process is to set the grayscale value of the pixel points on the image to 0 or 255, so that the entire image presents an obvious visual effect of only black and white.

[0053] Optionally, in this embodiment, the closing operation here refers to dilation and erosion processing of the binary candidate image in sequence, so as to fill the gaps or holes in the candidate image, connect adjacent objects, connect disconnected contours, and smooth the boundaries without changing the area.

[0054] Optionally, in this embodiment, performing a closing operation on the first candidate image and the second candidate image to obtain the first target image and the second target image includes:

[0055] 1) performing expansion processing on each page element in the first candidate image to obtain a plurality of first expanded image blocks; performing corrosion processing on each first expanded image block to obtain a plurality of first regular pattern blocks; determining the image containing the plurality of first regular pattern blocks as the first target image;

[0056] 2) Performing dilation processing on each page element in the second candidate image to obtain a plurality of second dilated image blocks; performing erosion processing on each second dilated image block to obtain a plurality of second regular graphic blocks; and determining the image containing the plurality of second regular graphic blocks as the second target image.

[0057] Specific combination Figure 5 The example shown is as follows: Assume that Figure 4 The i-th image group Gi is obtained from the image sequence as the current image group, and the first image and the second image are subjected to black-and-white binarization processing respectively to obtain the first candidate image and the second candidate image, as shown in FIG. Figure 5 The first candidate image has the title and publishing time loaded, while the second candidate image has the title, publishing time and page content loaded.

[0058] For each page element in the first candidate image (such as Figure 5 The title element and the publishing time element shown in (a) are closed, that is, the expansion process is first performed to obtain multiple first expansion blocks (such as Figure 5 As shown in (b), the gaps are filled and the disconnected parts are connected, and then the etching process is performed to obtain a plurality of first regular pattern blocks (such as Figure 5 Multiple rectangular solid blocks shown in (c)).

[0059] For each page element in the second candidate image (such as Figure 5 The title element, the publishing time element, and the text element shown in (d) are closed, that is, the expansion process is first performed to obtain multiple second expansion blocks (such as Figure 5 As shown in (e), the gaps are filled and the disconnected parts are connected, and then the etching process is performed to obtain a plurality of second regular pattern blocks (such as Figure 5 Multiple rectangular solid blocks as shown in (f)).

[0060] Then, a first target image including a plurality of first regular pattern blocks and a second target image including a plurality of second regular pattern blocks are compared to determine an image change rate between the two.

[0061] Through the embodiment provided by the present application, each image group in the image sequence is binarized in turn, and the obtained candidate images are closed to obtain regular graphic blocks corresponding to the page elements. Then, the regular graphic blocks in the above two images are compared to determine the image change rate, and then the page index parameters of the target page are accurately determined according to the image change rate.

[0062] As an optional solution, in the process of sequentially calculating the image change rate between two adjacent images in the image sequence, the following steps are also included:

[0063] Take each image change rate as the current image change rate and perform the following operations until the target image change rate is determined:

[0064] S1, compare the current image change rate with the target threshold;

[0065] S2, when the current image change rate is less than the target threshold, add one to the statistical result to obtain an updated statistical result, wherein the statistical result is used to indicate the number of image change rates less than the target threshold;

[0066] S3, when the updated statistical result is less than the convergence threshold, obtaining the next image change rate as the current image change rate;

[0067] S4, when the updated statistical result is equal to or greater than the convergence threshold, determining the current image change rate as the target image change rate.

[0068] Optionally, in this embodiment, after comparing the current image change rate with the target threshold, it can also include: when the current image change rate is greater than or equal to the target threshold, determining that the target page has not yet been loaded, no processing is performed, returning to the previous step, and continuing to obtain the next set of image change rates as the current image change rate.

[0069] Specific combination Figure 6 The example shown is used for illustration, assuming that the convergence threshold is set to M. The specific comparison process can be as follows:

[0070] After obtaining the current image change rate, compare the current image change rate with the target threshold. If the current image change rate is greater than or equal to the target threshold, obtain the next set of image change rates as the current image change rate. If the current image change rate is less than the target threshold, add one to the statistical result to obtain an updated statistical result.

[0071] When the updated statistical result is less than the convergence threshold M, the next image change rate is obtained as the current image change rate; when the updated statistical result is equal to or greater than the convergence threshold M, the current image change rate is determined as the target image change rate. Figure 6 As shown, it is determined that the current image change rate is less than the target threshold from the i-th group, then from G i When the change rate of M consecutive images is less than the target threshold, it is determined that the convergence condition is met, and the change rate of the Mth image (such as Figure 6 As shown in G i+(M-1) The image change rate corresponding to the group) is determined as the target image change rate.

[0072] Through the embodiments provided by the present application, each image change rate is compared and screened with the target threshold, and the number of image pairs whose image change rate is less than the target threshold is counted. When the statistical result indicates that the convergence threshold has been reached, it is determined that the convergence condition has been reached, so as to accurately determine the target image change rate used to determine the page index parameter, thereby ensuring the accuracy of the determination result of the page index parameter.

[0073] As an optional solution, the page loading video is sampled to obtain an image sequence including:

[0074] S1, taking screenshots of the page loading video at target intervals to obtain multiple images;

[0075] S2, sorting the multiple images according to the playback order to obtain an image sequence.

[0076] Optionally, in this embodiment, the target interval may be, but is not limited to, set to 200 ms. The interval configuration here is an optional example and is not limited in this embodiment.

[0077] For example, suppose a page loading video with a duration of 5 seconds is obtained, and then screenshots of the page loading video are taken at intervals of 200 ms to obtain 25 images. Then, the above 25 images are saved in sequence according to the playback order to obtain the above image sequence.

[0078] It should be noted that in this embodiment, when taking screenshots of the page loading video, the front-end application interface (Application Interface, API for short) and the function navigator.mediaDevices.getDisplayMedia() may not be used, but other screenshot software may be used, so that the operation can be performed without knowing the front-end technology at all.

[0079] Through the embodiments provided in the present application, by taking screenshots of the page loading video, an image sequence for image comparison is obtained, thereby ensuring the accuracy and efficiency of the page index parameter determination results.

[0080] As an optional solution, getting the page loading video includes:

[0081] S1, screen recording the target website that starts loading the target page;

[0082] S2, determining the recorded video within N seconds before recording as the page loading video, where N is a natural number greater than or equal to 1.

[0083] Optionally, in this embodiment, the above N can be, but is not limited to, set to a value greater than or equal to 1 and less than or equal to 5. The above recording can be, but is not limited to, starting from the moment the target page is loaded. The configuration of the recording duration here is an optional example, and this embodiment does not impose any limitation on this.

[0084] Optionally, in this embodiment, the screen of the target website (such as a browser) may be recorded by using, but not limited to, the following function: navigator.mediaDevices.getDisplayMedia().

[0085] It should be noted that in this embodiment, when performing screen recording processing on the page loading video, the front-end application interface (Application Interface, API for short) and the function navigator.mediaDevices.getDisplayMedia() may not be used, but other recording software may be used, so that the operation can be performed without knowing the front-end technology at all.

[0086] As an optional solution, screen recording the target website starting to load the target page includes one of the following:

[0087] 1) Calling a front-end application interface configured in a terminal device to perform screen recording of a target website, wherein the terminal device is a device that runs the target website and loads the target page; or

[0088] 2) Screen recording of the target website is performed through a third-party screen recording application client installed in the terminal device, where the terminal device is a device that runs the target website and loads the target page.

[0089] Optionally, in this embodiment, based on the loading time point corresponding to the target image change rate, determining the first screen time of loading the target page of the target website may include but is not limited to:

[0090] 1) Subtracting the loading time point of the second image in the target image group from the starting loading time point of the target page, and determining the difference obtained by the operation as the first screen time;

[0091] 2) Subtract the middle value of the loading time points of the first image and the second image in the target image group from the start loading time point of the target page, and determine the difference obtained by the calculation as the first screen time.

[0092] Through the embodiments provided in this application, obtaining the page indicator parameter first screen time of the target page from a non-pure front-end perspective will be more conducive to developers' understanding and operation, and the operation difficulty is briefly described, thereby achieving the purpose of improving determination efficiency.
