Exemplary embodiments of the present disclosure are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present disclosure to facilitate understanding, and should be considered as merely exemplary. Accordingly, one of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure.

In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.
Fig. 1 is a flowchart of an embodiment of a video repeatability obtaining method according to the present disclosure. As shown in fig. 1, the following detailed implementation is included.
In step 101, M frames of video images are extracted from the first video, where M is a positive integer greater than one and less than or equal to the total number of frames included in the first video, and corresponding reverse sequence images are respectively acquired for each extracted frame of video image.
In step 102, N frames of video images are extracted from the second video, where N is a positive integer greater than one and less than or equal to the total number of frames included in the second video, and for each extracted frame of video image, the similarity between the video image and each reverse sequence image is obtained.
In step 103, the repetition degree between the first video and the second video is determined according to the acquired similarity.
It can be seen that in the scheme of the embodiment of the method, video image extraction can be performed on the first video and the second video respectively, and the reverse sequence image of each video image extracted from the first video and the similarity between each video image extracted from the second video and each reverse sequence image can be obtained, so that the repeatability between the two videos can be determined according to the obtained similarity, the whole process is fast and easy to implement, the calculation resource and the time cost are saved, the processing efficiency is improved, and the like.
In the solution described in the present disclosure, there is no limitation on how to extract the video image from the first video, such as but not limited to: and taking each frame in the first video as an extracted video image, or extracting one frame of video image from the first video every interval of L frames, wherein L is a positive integer, and the specific value can be determined according to actual needs.
Assuming that 100 frames are included in the first video, all of the 100 frames may be taken as extracted video images, or assuming that L has a value of 1, one frame of video image may be extracted from the first video at 1 frame intervals, so that 50 frames of video images and the like are extracted in total.
Likewise, the manner in which video images are extracted from the second video may include, but is not limited to: and taking each frame in the second video as the extracted video image, or extracting one frame of video image from the second video every interval L frames.
Generally, the video image is extracted from the first video in the same way as the video image is extracted from the second video. For example, each frame in the first video may be used as an extracted video image, and each frame in the second video may be used as an extracted video image, or one frame of video image may be extracted from the first video at 1 frame intervals, and one frame of video image may be extracted from the second video at 1 frame intervals.
For the mode of taking each frame in the video as the extracted video image, more video images can be extracted, so that the accuracy of a subsequent processing result and the like can be improved, and for the mode of interval extraction, the number of the extracted video images can be reduced, and correspondingly, the workload of subsequent processing can be reduced, so that the processing efficiency and the like can be improved. Which way is adopted in particular can be determined according to actual needs.
After M frames of video images are extracted from the first video, the corresponding reverse sequence image may be acquired for each extracted frame of video image, as described in step 101. Specifically, for each extracted video image, the values of the pixel points in the video image can be respectively inverted, so as to obtain an inverted sequence image corresponding to the video image.
Assuming that 50 frames of video images, respectively numbered video image 1-video image 50, are extracted from the first video, an inverse sequence image corresponding to video image 1, an inverse sequence image corresponding to video image 2, an inverse sequence image corresponding to video image 3, … …, an inverse sequence image corresponding to video image 50, and the like can be obtained, respectively, so that 50 inverse sequence images can be obtained in total.
The extracted video image is typically a Bitmap (BMP) image, i.e., the extracted video image is stored in a memory in BMP format. For image storage, 256-bit artwork is typically used, and one Byte (Byte) represents the value of one pixel.
Correspondingly, for each frame of video image extracted from the first video, the Byte value of each pixel point in the video image can be respectively inverted, so that an inverted sequence image corresponding to the video image is obtained.
In practical application, after one frame of video image is extracted from the first video, the reverse sequence image corresponding to the video image is obtained, or after all M frames of video images are extracted, the corresponding reverse sequence images are respectively obtained for each video image. Which way is adopted in particular can be determined according to actual needs.
As described in step 102, N frames of video images may be extracted from the second video, and for each extracted frame of video image, a similarity between the video image and each of the reverse sequence images may be obtained.
Assuming that 50 frames of video images are extracted from the second video, respectively numbered as video image 101-video image 150, and assuming that there are 50 reverse-sequence images in total, then for video image 101, the similarity between video image 101 and each reverse-sequence image can be obtained, so that 50 similarities can be obtained, for video image 102, the similarity between video image 102 and each reverse-sequence image can be obtained, 50 similarities can be obtained, and so on.
In practical application, after one frame of video image is extracted from the second video, the similarity between the video image and each reverse sequence image can be obtained, or after all N frames of video images are extracted, the similarity between the video image and each reverse sequence image can be obtained for each video image. Which way is adopted in particular can be determined according to actual needs.
Specifically, for each frame of video image extracted from the second video, the following processing may be performed, respectively: and carrying out coupling operation on the video image and each reverse sequence image to obtain M coupling result images, wherein the sizes of the video image, the reverse sequence image and the coupling result images are the same, counting the number of pixels with non-zero values in the coupling result images respectively aiming at each coupling result image, and taking the counting result as the similarity between the video image and the reverse sequence image corresponding to the coupling result image, wherein for any pixel in the coupling result image, if the value of the corresponding pixel in the video image is the same as the value of the corresponding pixel in the reverse sequence image, the value of the pixel can be set to zero, otherwise, the pixel is not zero, and the corresponding pixel is the pixel with the same position.
In the scheme of the disclosure, the extracted video image may be any size, and may be preprocessed, that is, adjusted to a predetermined size, and after adjustment, the size of the extracted video image from the first video, the size of the extracted video image from the second video, the size of the anti-sequence image, or the size of the coupling result image are the same, that is, the predetermined size. The specific value of the predetermined size can be determined according to actual needs.
For each frame of video image extracted from the second video, the video image can be respectively coupled with M reverse sequence images, so that M coupling result images are obtained. For example, for each reverse sequence image, corresponding pixel points in the video image and the reverse sequence image can be respectively processed according to Byte and operation, so that a coupling result image corresponding to the reverse sequence image is obtained, the number of pixel points with a value different from zero in the coupling result image can be counted, and the counted result is used as the similarity between the video image and the reverse sequence image.
When a certain video image and a certain anti-sequence image are coupled, namely, when corresponding pixel points in the video image and the anti-sequence image are subjected to Byte and operation, taking the pixel point with the coordinate position of (10, 10) in the obtained coupling result image as an example, if the value of the pixel point with the coordinate position of (10, 10) in the video image is the same as the value of the pixel point with the coordinate position of (10, 10) in the anti-sequence image, the pixel point with the coordinate position of (10, 10) in the coupling result image can be set to be 0, otherwise, the pixel point can be set to be 1, the number of the pixel points with the coordinate position of not being 0 in the coupling result image can be counted, and the counted result can be used as the similarity between the video image and the anti-sequence image.
Thus, for each frame of video image extracted from the second video, the following result sets may be obtained, respectively:
A1 A2 A3 …
B1 19 5 10 …
wherein B1 represents one frame of video image extracted from the second video, A1, A2, A3, etc. represent each frame of video image extracted from the first video, 19 represents the similarity between the video image B1 and the reverse sequence image corresponding to the video image A1, 5 represents the similarity between the video image B1 and the reverse sequence image corresponding to the video image A2, and so on.
According to the result set corresponding to each video image extracted from the second video, a result matrix of N rows and M columns can be generated.
The ith row in the result matrix corresponds to the ith frame of video image extracted from the second video, i is less than or equal to 1 and less than or equal to N, the ith frame of video image represents the video image at the ith position after the N frames of video images extracted from the second video are sequenced according to the sequence from the beginning to the end of the extraction time, the jth column in the result matrix corresponds to the jth frame of video image extracted from the first video, j is less than or equal to 1 and less than or equal to M, the jth frame of video image represents the video image at the jth position after the M frames of video images extracted from the first video are sequenced according to the sequence from the beginning to the end of the extraction time, and each element in the result matrix represents the similarity between the video image corresponding to the row and the reverse sequence image of the video image corresponding to the column.
The result matrix may be as follows:
wherein B1, B2, B3, etc. represent each frame of video image extracted from the second video, A1, A2, A3, etc. represent each frame of video image extracted from the first video, respectively, and A1 is the video image extracted from the first video first, A2 next, and so on, and similarly B1 is the video image extracted from the second video first, B2 next, and so on.
The degree of repetition between the first video and the second video may be determined based on the result matrix. Specifically, under the principle that the path length is as long as possible and the sum of elements on the path is as small as possible, the two factors of the path length and the sum of elements on the path can be balanced, an optimal continuous path is determined from a result matrix, rows of the elements on the optimal continuous path are different, columns of the elements are different, and the repeatability between the first video and the second video can be determined according to the path length of the optimal continuous path, the sum of elements on the optimal continuous path, M and the number of pixel points included in the video image.
When determining the optimal continuous path from the result matrix, it is desirable that the path length is as long as possible, and the sum of the elements on the path is as small as possible, and the smaller the path length is, the larger the similarity is, the larger the number of similar frames is, but the sum of the elements on the path length and the path is two mutually influencing factors, for example, the increase of the path length may cause the sum of the elements on the path to be increased, so that the two factors need to be balanced, and the result of comprehensively evaluating the optimal, namely the optimal continuous path, is selected according to the time continuity of the frames. Or it may be understood that, for the factor of the path length, the score is higher as the value is larger, and for the factor of the sum of the elements on the path, the score is higher as the value is smaller, and when the score of one factor is increased, the score of the other factor may be reduced, so that the two factors need to be balanced, and the optimal continuous path with the highest comprehensive score is selected.
As shown in fig. 2, fig. 2 is a schematic diagram of an optimal continuous path according to the present disclosure. How to determine the optimal continuous path from the result matrix is not limited, and various existing maturation algorithms can be used.
And determining the repeatability between the first video and the second video according to the path length of the optimal continuous path, the sum of the addition of the elements on the optimal continuous path, M and the number of pixel points included in the video image.
For example, a quotient of the sum of the elements on the optimal continuous path and the number of pixels included in the video image may be calculated, and a quotient of the path length of the optimal continuous path and M may be calculated, and then a product of the two quotients may be calculated, and the product may be used as the repetition degree between the first video and the second video.
The method comprises the following steps: result= (P/W) × (MaxLength/M); (1)
Wherein P represents the sum of the elements on the optimal continuous path, W represents the number of pixels included in the video image, maxLength represents the path length of the optimal continuous path, M represents the number of video images extracted from the first video, and Result represents the degree of repetition.
As can be seen from the above description, fig. 3 is a schematic diagram of an overall implementation process of the video repeatability obtaining method according to the present disclosure, and the detailed implementation is referred to the above related description and will not be repeated.
