[0076] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0077] The embodiments of this application provide a video processing method, referring to... Figure 1 As shown, the method is applied to a video processing device, and the method includes the following steps:

[0078] Step 101: Obtain the video image data to be processed collected by the image acquisition device of the flight equipment and the flight speed set of the flight equipment during the acquisition of the video image data to be processed.

[0079] In this embodiment, the flight device can be a flying device, such as a drone. The image acquisition device is a camera device or lens module with image acquisition function. The flight device activates the image acquisition device and performs flight photography during flight to obtain video image data to be processed. In one embodiment, the flight device records the actual flight speed in real time according to a preset recording interval during flight to obtain a flight speed set. The speed acquisition time in the flight speed set is consistent with the time in the video image data to be processed.

[0080] Video processing equipment is a device capable of communicating with flight equipment. Communication can occur via wired or wireless means, and it must at least transmit the video image data and flight speed data acquired by the flight equipment. The video processing equipment must also possess computing power. When data transmission occurs between the video processing equipment and the flight equipment via wireless communication, the wireless communication method can be Bluetooth, short-range wireless communication, the Internet, or similar methods.

[0081] In some application scenarios, video processing equipment can be integrated with flight equipment or can be a terminal device independent of flight equipment, such as smart mobile terminal devices or various types of computer equipment.

[0082] In some application scenarios, video processing equipment can acquire video image data to be processed from a smart head-mounted device that has a communication link with the flight equipment. After the flight equipment acquires images during flight, it sends the video image data to be processed to the smart head-mounted device. The smart head-mounted device then sends the video image data to be processed back to the video processing equipment via wired or wireless communication. The smart head-mounted device can be a smart glasses device, a smart visualization helmet, or similar device.

[0083] Step 102: Determine at least one adjustment speed.

[0084] Among them, the video image data to be processed, the flight speed of the flight speed set, and at least one adjustment speed have a corresponding relationship in time.

[0085] In this embodiment, at least one adjustment speed is determined based on the relevant feature parameters corresponding to the video image data to be processed. The at least one adjustment speed is the flight speed at which the desired flight device acquires the video image data. In one embodiment, a single adjustment speed can be uniformly applied to a segment of video to be processed, thus achieving the video effect obtained by flight acquisition at the same flight speed. Of course, multiple adjustment speeds can be set for a segment of video to be processed; for example, the video to be processed can be divided into multiple sub-video segments, and an adjustment speed can be set for each sub-video segment.

[0086] The adjustment speed can be set manually or automatically. For example, it can be automatically set to a suitable adjustment speed based on flight altitude or camera movement mode. When manually setting the adjustment speed, there are multiple interaction methods available. For instance, users can be provided with operation buttons to adjust the speed. The specific method for determining the adjustment speed is not limited here.

[0087] Step 103: Determine the playback rate of the video image data to be processed based on the flight speed set and at least one adjustment speed.

[0088] In this embodiment, the playback rate of the video image data to be processed is determined by analyzing the flight speed of the flight speed set and the corresponding speed of at least one adjustment speed. The playback rate of the video image data to be processed may be different in different playback time periods; that is, the playback rate may include one or more different rates according to the distribution of playback time. Specifically, the ratio of the actual flight speed at the same moment to the corresponding adjustment speed at that moment is taken as the playback rate at that moment.

[0089] Step 104: Play the video image data to be processed according to the playback rate.

[0090] Specifically, the video image data to be processed is played according to the playback rate, so as to achieve the playback effect of playing the video image data collected when the flight equipment flies at at least one adjusted speed.

[0091] In this embodiment of the application, when the video processing device plays the video image data to be processed, it may play and display the data on the screen display area of ​​the video processing device, or it may send the playback rate and the video image data to be processed to a video playback device with which it has a communication link for playback and display.

[0092] The video image data to be processed is played according to a determined playback rate. The number of playback frames of the video image data to be processed within the corresponding time period is adjusted. This achieves the effect of playing video data collected by the flight equipment at different time periods according to the corresponding adjustment speed, ensuring the smoothness of the playback of the video image data to be processed, improving the playback quality of the video image data to be processed, and further ensuring the user experience.

[0093] The video processing method provided in this application involves acquiring video image data to be processed from the image acquisition device of a flight device and the flight speed set of the flight device during the acquisition process. Then, at least one adjustment speed is determined. Based on the flight speed set and the at least one adjustment speed, a playback rate for the video image data to be processed is determined. Finally, the video image data is played according to the playback rate, achieving a playback effect of playing video image data acquired when the flight device flies at at least one adjustment speed. In this way, the playback rate is calculated and analyzed based on the determined at least one adjustment speed and the speed in the flight speed set of the flight device. Playing the video image data to be processed acquired by the flight device according to this playback rate makes the playback smoother, solving the problem of low smoothness of video data acquired by drones. This method provides a video processing method for processing video data acquired by drones, ensuring smooth playback of video image data acquired by drones and improving the playback quality of video image data acquired by drones.

[0094] Based on the foregoing embodiments, embodiments of this application provide a video processing method, which is applied to a video processing device, and includes the following steps:

[0095] Step 201: Obtain the video image data to be processed collected by the image acquisition device of the flight equipment and the flight speed set of the flight equipment during the acquisition of the video image data to be processed.

[0096] In this embodiment of the application, a remote-controlled drone equipped with a camera is used as an example of the flight equipment. During the flight, the drone’s flight speed is controlled by the user. During the flight, the drone’s camera is always working to capture the corresponding target in the flight environment and obtain video image data to be processed. During the flight, the drone continuously collects and records its flight speed at a certain sampling interval to obtain a flight speed set.

[0097] For example, between 13:00 and 13:30, the user controls the drone's camera to capture images of a target, such as the ground, obtaining video image data to be processed within the corresponding half-hour, as well as the distribution of the drone's flight speed during this half-hour, thus obtaining a flight speed set. The drone can actively or passively send the collected video image data and flight speed set to the video processing device. For example, in the case of active transmission, the drone can immediately send the collected video image data and flight speed set to the video processing device after detecting that a communication link has been established, ensuring that the drone has sufficient storage space to detect the video processing device. In the case of passive transmission, after the communication link between the drone and the video processing device is established, the video processing device sends a request to the drone to obtain the video image data and flight speed set, and then the drone responds to the request before sending the corresponding video image data and flight speed set to the video processing device.

[0098] Step 202: Determine at least one adjustment speed.

[0099] Among them, the video image data to be processed, the flight speed of the flight speed set, and at least one adjustment speed have a corresponding relationship in time.

[0100] In this application embodiment, at least one adjustment speed can be calculated by the video processing device according to the flight characteristic parameters of the flight device, such as flight speed or flight altitude, according to a preset algorithm; it can also be set by the user based on experience and needs; or it can be determined according to other requirements, such as the operating parameters of the image acquisition device.

[0101] Step 203: Determine the playback rate of the video image data to be processed based on the flight speed set and at least one adjustment speed.

[0102] In this embodiment, the video processing device compares and analyzes the set of flight speeds and at least one adjustment speed according to a preset empirical analysis method between flight speed and adjustment speed, and determines the corresponding playback rate of the video image data to be processed. In other words, the playback rate of the video image data to be processed is determined at least by its corresponding set of flight speeds and at least one adjustment speed.

[0103] Step 204: Play the video image data to be processed according to the playback rate.

[0104] Specifically, the video image data to be processed is played according to the playback rate, so as to achieve the playback effect of playing the video image data collected when the flight equipment flies at at least one adjusted speed.

[0105] In this embodiment of the application, when the video processing device has a screen display area, the video processing device can display the video image data to be processed playing at the playback rate in the screen display area.

[0106] It should be noted that in some application scenarios, steps 201-204 can be operations executed only when the video processing device detects a playback command. In other application scenarios, to ensure playback efficiency, steps 201-203 can also be executed before the playback command is detected. For example, the video processing device can execute these operations immediately after receiving the video image data to be processed, and step 204 can be executed only after the playback command is detected. The playback command can be automatically generated by the video processing device based on playback requirements, or it can be generated by the user when there is a playback requirement.

[0107] Based on the foregoing embodiments, in other embodiments of this application, step 202 can be implemented by steps 202a to 202b:

[0108] Step 202a: Obtain the set of flight altitudes of the flight equipment during the process of the image acquisition device acquiring the video image data to be processed.

[0109] In this embodiment of the application, during flight, the flight device not only collects video image data to be processed, but also records its flight altitude parameters to obtain a flight altitude set. The flight device then sends the collected flight altitude set to the video processing device.

[0110] Step 202b: Based on the set of flight altitudes, determine at least one adjustment speed.

[0111] In this embodiment, the video processing device analyzes the flight altitude parameters in the flight altitude set to determine at least one adjustment speed. The adjustment speed corresponding to the flight altitude parameter can be calculated using empirical formulas. Alternatively, the adjustment speed corresponding to the flight altitude parameter in the flight altitude set can be found in an empirical list of flight altitudes and adjustment speeds, thus obtaining at least one adjustment speed.

[0112] Based on the foregoing embodiments, in other embodiments of this application, step 202b can be implemented by the following steps: determining the speed corresponding to each flight altitude in the set of flight altitudes from the preset flight altitude and speed relationship, and obtaining at least one adjustment speed; wherein, in the preset flight altitude and speed relationship, flight altitude and speed are positively correlated.

[0113] In this embodiment, the preset relationship between flight altitude and speed can be an empirical calculation formula or an empirical value list of different speed values ​​corresponding to different altitudes. In the preset relationship between flight altitude and speed, the relationship between flight altitude and speed is positively correlated, that is, the higher the flight altitude, the greater the corresponding speed, i.e., the greater the flight speed. In this way, users can clearly perceive the changes in the subject being photographed when the flight device flies at a higher flight altitude, ensuring the user's perception experience when viewing the video image data collected by the flight device.

[0114] For example, the flight speed is uniformly adjusted to a preset speed for the corresponding altitude. For instance, the preset speed is 30 kilometers per hour (km / h) for an altitude of 0-20 meters (m), and 60 km / h for an altitude of 20-50 meters, and so on. Figure 2 The image shows the distribution curves of flight speeds within the flight speed set. Correspondingly, according to... Figure 2 The two speed adjustment distribution diagrams obtained from determining the flight altitude can be shown as follows: Figure 3 As shown. In Figure 2 and Figure 3 In the diagram, the vertical axis represents the velocity axis, and the horizontal axis represents the time axis.

[0115] In some application scenarios, for Figure 2 The distribution curve of flight speed in the set of flight speeds shown can be adjusted when necessary. Figure 2 A virtual button for "one-click smoothing" is provided. Figure 2 (Not shown in the image), so that after the user touches the displayed "one-click smoothing" virtual button according to actual needs, the video processing device calls the specific implementation methods of steps 202a-202b to generate... Figure 3 The speed adjustment is shown.

[0116] Based on the foregoing embodiments, in other embodiments of this application, step 202 can be implemented by steps 202c to 202d:

[0117] Step 202c: Determine the set of camera movement modes corresponding to the process of the image acquisition device acquiring the video image data to be processed.

[0118] In this embodiment, the camera movement pattern set of the image acquisition device refers to the movement actions of the flying device carrying the image acquisition device during the process of acquiring video image data to be processed. Examples include actions such as soaring upwards, spiraling, swishing, and jumping. The camera movement patterns in the camera movement pattern set are recorded according to a time distribution, and these patterns can repeat multiple times in different time periods, specifically determined by the actual application scenario of the image acquisition device.

[0119] Step 202d: Based on the set of camera movement modes, determine at least one adjustment speed.

[0120] In this embodiment, a corresponding adjustment speed is pre-set for different camera movement modes. The adjustment speed for different camera movement modes may include more than one speed, and may be a certain set of speed distributions according to the camera movement time distribution.

[0121] Based on the foregoing embodiments, in other embodiments of this application, step 202d can be implemented by the following steps: determining at least one preset speed corresponding to each camera movement mode in the camera movement mode set from the preset camera movement mode and speed relationship, and obtaining at least one adjustment speed.

[0122] In this embodiment, the preset camera movement mode and speed relationship can be a speed distribution calculation algorithm pre-set between preset camera movement modes and speeds under different camera movement modes, or it can be an empirical speed value distribution, for example, represented by a speed distribution curve. Thus, after determining the set of camera movement modes for the image acquisition device, at least one preset speed can be obtained from the preset camera movement mode and speed relationship for each camera movement mode in the set. By arranging the at least one preset speed according to the distribution of camera movement modes in the set, at least one adjustable speed can be obtained.

[0123] For example, based on Figure 2 The distribution curves of flight speeds in the set of flight speeds shown indicate that when the camera movement mode is detected as "skyward," the distribution pattern of at least one preset speed is slow, fast, slow. The corresponding curve distribution can be referenced. Figure 4 As shown.

[0124] Based on the foregoing embodiments, in other embodiments of this application, step 202 can also be implemented by steps 202e to 202f:

[0125] Step 202e: Detect the touch operation of the video processing device to determine the touch area for speed adjustment.

[0126] In this embodiment, the touch area can be the area where physical buttons are located. That is, after the user controls these physical buttons to adjust the speed settings, a corresponding touch operation is generated that can be perceived by the video processing device. The touch area can also be the touch-enabled screen display area of ​​the video processing device. Correspondingly, the user can perform touch operations on the touch area, allowing the video processing device to determine the touch trajectory within the touch area and thus obtain the touch operation related to the speed adjustment settings. The user's touch operation on the touch area can be by touching virtual buttons displayed in the touch area, or by performing corresponding touch operations on the displayed image content.

[0127] Step 202f: Based on the touch operation, determine at least one adjustment speed.

[0128] In this embodiment, the video processing device analyzes the touch operation to determine at least one adjustment speed set by the user through the touch area.

[0129] Based on the foregoing embodiments, in other embodiments of this application, step 202e can be implemented by steps a11 to a12:

[0130] Step a11: Display a virtual button for adjusting the speed in the display area corresponding to the video processing device.

[0131] In this embodiment of the application, the display area corresponding to the video processing device can be the screen display area of ​​the video processing device, which displays the distribution curve of the flight speed set over time, and also displays a virtual button for setting and adjusting the speed.

[0132] Step a12: Detect the touch press trajectory of the touch object on the virtual button in the touch area to obtain the touch operation.

[0133] In this embodiment, the touch object can be a stylus, a user's finger, or any other object that performs touch operations on the touch area. The touch area and the display area may be the same area or different areas, depending on the actual configuration of the video processing device.

[0134] For example, a user can touch the virtual button in the image and drag it along the horizontal line at the desired speed to create a continuous operation trajectory, or, as... Figure 5 As shown, during the display of the concentrated speed value curve, the speed distribution can be adjusted by changing the position of the virtual button on the speed distribution adjustment progress bar on the right. Specifically: Figure 5 The thick solid line indicates that the virtual button on the speed distribution progress bar is set to position 6.3, thus setting the speed adjustment to 6.3 m / s. In this way, the touch operation is detected and recognized by the operation trajectory.

[0135] Based on the foregoing embodiments, in other embodiments of this application, step 202e can also be implemented by steps b11 to b12:

[0136] Step b11: Display the flight speed curve of the flight device corresponding to the flight speed set in the display area corresponding to the video processing device.

[0137] In this embodiment of the application, the video processing device plots a flight speed curve that is distributed over time based on the flight speed of the flight speed concentration, and displays the plotted flight speed curve.

[0138] Step b12: In the touch area, detect the touch operation of the touch object selecting a point on the flight speed curve.

[0139] In this embodiment, after displaying the flight speed curve, the user can make touch selections in the touch area. Based on the curve distribution of the flight speed curve, the user selects several independent touch points, which are then displayed using graphic icons. Finally, these touch points are connected by a smooth curve in chronological order of flight time to obtain the touch operation, thereby determining at least one adjustment speed. For example, as shown... Figure 6 As shown, users can select multiple points by touching different locations based on the distribution curve of the flight speed set displayed in the display area. Virtual button-like graphic icons are set at the selection points for intuitive display to prompt the user to select the point. Finally, multiple virtual buttons are connected in order of flight time using a smooth curve to obtain at least one speed adjustment corresponding to the touch operation. Figure 6 The thin solid lines represent concentrated flight speed distributions, while the buttons on the thick solid lines display the speed corresponding to the selected point. The thick solid lines also represent the final adjusted speed distribution. Alternatively, as shown... Figure 7 As shown, users can select multiple points on the flight speed distribution curve displayed in the display area to break the selected speed, and then optimize the speed based on these multiple selection points to obtain the desired result. Figure 8 The speed distribution is shown.

[0140] Based on the foregoing embodiments, in other embodiments of this application, step 203 can be implemented by steps 203a to 203b:

[0141] Step 203a: Based on the flight velocity set, determine the analysis velocity corresponding to each moment.

[0142] In this embodiment, the flight speeds included in the flight speed set are analyzed to determine the analysis speed corresponding to each moment within the flight speed set. The analysis speed can be the flight speeds included in the flight speed set, or it can be determined by calculating and analyzing multiple flight speeds in the flight speed set. When determining the analysis speed corresponding to each moment, the speeds in the flight speed set can be segmented in a segmented manner, and the flight speeds within each time range can be analyzed to determine the analysis speed corresponding to each moment.

[0143] Step 203b: Determine the playback rate corresponding to each moment based on the analysis speed corresponding to each moment and the adjustment speed corresponding to at least one adjustment speed at the same moment.

[0144] In this embodiment of the application, when playing video image data to be processed, the analysis speed corresponding to each moment and the adjustment speed of at least one adjustment speed corresponding to the moment are analyzed to determine the playback rate corresponding to each moment.

[0145] Correspondingly, step 204 can be achieved by the following steps: playing the video image data to be processed according to the playback rate corresponding to each moment.

[0146] In this embodiment of the application, after determining the playback rate corresponding to each moment, the video processing device plays the video image data to be processed according to the determined playback rate corresponding to each moment.

[0147] Based on the foregoing embodiments, in other embodiments of this application, step 203a can be implemented by steps c11 to c13:

[0148] Step c11: Segment the video image data to be processed to obtain m segments of sub-video image data.

[0149] Where m is a positive integer greater than or equal to 1.

[0150] In this embodiment of the application, the video image data to be processed is segmented according to a pre-set segmentation rule to obtain m segments of sub-video image data, where m is determined by the actual segmentation situation and its minimum value is 1.

[0151] Step c12: From the flight speed set, obtain the flight speed subset corresponding to each sub-video image data.

[0152] In this embodiment of the application, the speed of the flight speed set is also segmented according to the corresponding time distribution of each sub-video image data to obtain m corresponding flight speed subsets.

[0153] Step c13: Based on each subset of flight speeds, determine the analysis speed corresponding to each moment.

[0154] In this embodiment of the application, the video processing device analyzes the speed of each flight speed subset to determine the analysis speed distribution within the time period corresponding to each sub-video image data, thereby obtaining the analysis speed corresponding to each moment.

[0155] Based on the foregoing embodiments, in other embodiments of this application, step c11 can be implemented by step c111 or step c112:

[0156] Step c111: Divide the video image data to be processed into segments according to the preset segment duration to obtain m segments of sub-video image data.

[0157] In this embodiment, the preset segment duration is an empirical duration obtained from a large number of experiments, or an empirical duration set by the user based on their own experience. In actual application, it can be continuously adjusted according to actual needs. For example, assuming the preset segment duration is s seconds, the video image data to be processed is segmented from the beginning at intervals of s seconds, thereby obtaining m segments of sub-video image data.

[0158] Step c112: According to the segmentation rule that the fluctuation range of flight speed within a continuous time period is within a preset threshold range, the video image data to be processed is segmented to obtain m segments of sub-video image data.

[0159] In this embodiment, the preset threshold can be an empirical value of flight speed deviation obtained from a large number of experiments. In actual application, it can be set according to actual needs. For example, taking the flight speed u1 corresponding to the video image data to be processed at second 0 as a benchmark, it is determined whether the flight speed in the continuous time period starting from second 0 is within the range of u1±Δ. When it is detected that the flight speed at second j exceeds the range of u1±Δ, the video image data to be processed is segmented at second j-1 to obtain the first segment of video image data with a duration range from second 0 to second j-1. Then, taking the flight speed u2 at second j as a benchmark, it is determined that when the flight speed at second k in the subsequent continuous time period exceeds the range of u2±Δ, the video image data to be processed is segmented at second k-1 to obtain the second segment of video image data with a duration range from second j to second k-1. This process is repeated until the last second of the video image data to be processed is segmented. During this process, the duration of each segment of video image data may be different.

[0160] Based on the foregoing embodiments, in other embodiments of this application, step 203b can be implemented by steps d11 to d12:

[0161] Step d11: Calculate the ratio of the adjustment speed to the analysis speed at each moment.

[0162] In this embodiment of the application, it is assumed that the adjustment speed at time i is u. mi The corresponding analysis velocity obtained at time i is u. fi Then the ratio B corresponding to time i is i B can be calculated using the following formula: i =u mi / u fi .

[0163] Step d12: Determine the corresponding playback rate based on the ratio at each moment.

[0164] In this embodiment of the application, the playback rate of the video image data to be processed at the corresponding moment is adjusted according to the ratio corresponding to each sub-video image data to obtain the corresponding playback rate.

[0165] For example, after segmenting the video image data to be processed to obtain m segments of sub-video image data, the adjustment speed corresponding to each sub-video image data is determined from at least one adjustment speed to obtain the target speed. Then, based on each subset of flight speeds and the corresponding target speed, the playback rate corresponding to each sub-video image data is determined, wherein the playback rate includes m sets of sub-playback rates.

[0166] Specifically, for at least one adjustment speed, according to the time distribution corresponding to each sub-video image data, the at least one adjustment speed is also segmented according to the time distribution to obtain the target speed corresponding to m sub-video image data. The i-th flight speed subset and the corresponding i-th target speed are analyzed to determine the sub-playback rate corresponding to the i-th sub-video image data, where i takes the value of 1, 2, ..., m.

[0167] Correspondingly, the corresponding sub-video image data can be played according to the sub-playback rate of each sub-video image data, thus realizing the process of playing the video image data to be processed according to the corresponding playback rate at each moment.

[0168] Based on the foregoing embodiments, in other embodiments of this application, step c13 can be implemented by step c131 or steps c132 to c133:

[0169] Step c131: From each subset of flight speeds, determine the nth flight speed as the analysis speed.

[0170] Where n is less than or equal to the total number of elements included in each flight speed subset.

[0171] In this embodiment, n is an empirical value, which can be determined based on the total number of items included in each flight speed subset, or it can be a directly specified empirical value, such as the flight speed corresponding to a specific second in the sub-video image data for each flight speed subset. For example, the first flight speed in each flight speed subset is determined as the analysis speed of the corresponding sub-video image data. In some application scenarios, the speed with the highest frequency in each flight speed subset can also be determined as the analysis speed.

[0172] Step c132: Calculate the average speed of the flight speeds included in each subset of flight speeds.

[0173] In the embodiments of this application, the average speed of each flight speed subset is calculated using an average value calculation method or a weighted average value calculation method.

[0174] Step c133: Determine the analysis speed as the average speed.

[0175] In this embodiment of the application, the analysis speed of the sub-video image data corresponding to each subset of flight speeds is determined as the calculated average speed.

[0176] For example, such as Figure 9 As shown, the video image data to be processed can be divided into two segments based on time, one segment with a duration of 'a' and the other segment with a duration of 'b'. The analysis speed for the sub-video image data in segment 'a' is determined to be x m / s, and the analysis speed for the sub-video image data in segment 'b' is determined to be y m / s. Assuming the determined adjustment speed is z m / s, the video playback rate for the sub-video image data in segment 'a' can be determined to be (z / x) * P frames / s, and the video playback rate for the sub-video image data in segment 'b' is determined to be (z / y) * P frames / s, where P frames / s is the playback rate of the video image data to be processed when played at normal 1x speed.

[0177] Based on the foregoing embodiments, in other embodiments of this application, step d12 can be implemented by step d121 or step d122:

[0178] Step d121: If the ratio at each moment is greater than 1, perform frame skipping playback on the image frame data at the corresponding moment according to the ratio to obtain the playback rate corresponding to the ratio.

[0179] In this embodiment, when the ratio is greater than 1, the corresponding video image data frame is subjected to frame skipping playback processing according to the ratio, thereby speeding up the playback rate of the video image data at that moment and obtaining the playback rate corresponding to the ratio.

[0180] Step d122: If the ratio corresponding to each moment is less than 1, perform frame interpolation on the image frame data at the corresponding moment according to the ratio to obtain the playback rate corresponding to the ratio.

[0181] In this embodiment of the application, when the ratio is less than 1, the video image data at the corresponding moment is subjected to frame interpolation playback processing according to the ratio, and the playback rate of the video image data at that moment is reduced.

[0182] This enables variable-speed playback of aerial videos, ensuring smooth playback and improving video image quality.
