[0030] Such as figure 1 As shown, this application provides a video review method, including the following steps:

[0031] Step 101: Obtain N image frames of the video to be reviewed.

[0032] The above-mentioned N is an integer greater than 1, and the above-mentioned N image frames can be all image frames of the video to be reviewed, or part of the image frames selected from all the image frames of the video to be reviewed according to a certain step size or interval . If the video to be reviewed is long, in order to reduce the required calculation time, some image frames may be selected from all the image frames of the video to be reviewed as the above N image frames according to a certain step size or interval. The image frames of the video to be reviewed can be decoded by Ffmpeg to obtain the above N image frames.

[0033] Video review is based on extracting review frames from videos to be reviewed. The number of review frames and the quality of review frames are two im...

Abstract

The invention discloses a video auditing method, a video auditing device and electronic equipment, and relates to the technical field of video auditing. The video auditing method comprises the steps: acquiring N image frames of a video to be audited, wherein N is an integer greater than 1; obtaining an inter-frame difference change value of the N image frames, wherein the inter-frame difference change value is used for representing a difference degree between two adjacent image frames; and selecting an image frame corresponding to a target inter-frame difference change value as an auditing frame, wherein the target inter-frame difference change value is an inter-frame difference change value which is not greater than the adjacent inter-frame difference change value in the inter-frame difference change values of the N image frames. According to the method and the device, the inter-frame difference change value of the plurality of image frames of the to-be-audited video is acquired and is used as the basis for selecting the audit frame, so that the selected audit frame has relatively high stability, the video audit effect can be improved, and the problem that the video audit effect is relatively poor in the prior art is solved.

Description

technical field [0001] The present application relates to data processing technology, in particular to the technical field of video review, in particular to a video review method, a video review device and electronic equipment. Background technique [0002] With the development of Internet technology, the number of videos on the Internet is increasing day by day, and the efficiency and accuracy of video review are becoming more and more important. During the video review process, it can be reviewed frame by frame or by extracting review frames for review. Since frame by frame review is time-consuming, the method of extracting review frames is generally used at present. In the prior art, it is generally used to extract review frames at time intervals, however, the stability of the extracted review frames is difficult to guarantee, which leads to a poor effect of video review. Contents of the invention [0003] The application provides a video review method, a video review ...
