Problems solved by technology

The disadvantage of this method is: if the transcoded video does not pass the review, the previous transcoding work will be invalid, resulting in a waste of resources; in addition, because the videos in the prior art are reviewed one by one, the review progress relatively low
At present, due to the speed of video review, some videos cannot be uploaded to the video website in time

Embodiment Construction

[0025] Now in conjunction with accompanying drawing, invention is described in further detail. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the invention in a schematic way, so they only show the configurations related to the invention.

[0026] As shown in the figure, a quick video review method includes the following steps:

[0027] Step 1: Input the review type, uniformly input the review type of the video to be reviewed into the system preprocessing system;

[0028] Step 2: Boundary shot extraction and similar frame filtering. First, image features are extracted based on different feature colors, textures, and contours of the image; then, the inter-frame similarity is calculated based on the extracted image features, and the image is judged based on adaptive or custom thresholds Whether it is similar, so as to simplify the video or extract the shot boundary;

[0029] In the similar frame filtering algorithm, the metho...

Abstract

The present invention relates to the fields of multimedia information (picture and video), machine vision, and computational vision, and in particular to a method for fast video review, in which parameters are automatically assigned by the system to complete shot boundary extraction or similarity filtering, and then the extracted boundary frames are Combining a short video, and finally reviewing personnel or an automatic system to review the short video is a fast video review method, including step 1: input review type, uniformly input the review type of the video to be reviewed into the system preprocessing system; step 2 : Boundary lens extraction and similar frame filtering, step 3: video synthesis, using the open source tool ffmpeg (for example: ffmpeg‑fimage2‑i%d.jpg‑vcodec libx264‑rN test.mp4) command to generate a frame rate of N frames / s Step 4: Video review output, the generated video output with a frame rate of N frames / s is convenient for manual or system review.

Description

technical field [0001] The invention relates to the fields of multimedia information (picture and video), machine vision, and computer vision, and in particular to a method for fast video review. Background technique [0002] As multimedia technology and applications become more and more extensive, various videos and audios are widely collected and released, and their contents and types emerge in endlessly and are complicated. Therefore, the review of copyright, politics, pornography and violence in videos is becoming more and more important, and the number of video reviews is also increasing. [0003] At present, most companies with audit qualifications are almost 1:1 audit, whether it is manual audit or automatic audit, which means that the audit must play the video in its entirety, which is time-consuming and labor-intensive. [0004] In the prior art, before the video is "on the shelf", all the videos to be uploaded are generally transcoded first, and then each video re...
