Problems solved by technology

The video fingerprint based on spatial color is basically generated by using the histogram of a specific area of ​​the picture in a certain time period, and because the color characteristics will change according to different video formats, it will cause the video fingerprint based on spatial color to be inconsistent. It has high anti-noise ability, and the video fingerprint based on spatial color does not have enough anti-noise ability to add trademarks, black borders and other changes

Abstract

The embodiment of the invention discloses a video data processing method and apparatus. The method comprises the following steps: performing frame rate change on source video data to obtain target video data, and obtaining SIFT features corresponding to each frame of data in the target video data; performing redundant processing and two-dimensional transformation processing on the SIFT features to obtain a video fingerprint feature vector corresponding to the target video data; searching pre-stored video data having the highest matching degree with the target video data from a preset video fingerprint feature matching library according to the video fingerprint feature vector corresponding to the target video data, and when the matching degree between the searched pre-stored video data and the target video data is greater than a preset matching degree threshold, determining the source video data as illegal video data. By adoption of the video data processing method and apparatus, the anti-noise ability of the video fingerprint can be improved.

Description

technical field [0001] The present invention relates to the technical field of the Internet, in particular to a video data processing method and device. Background technique [0002] With the development of the Internet, there are more and more online videos on the Internet, and copyright protection for some original videos is becoming more and more important. Currently, content-based copyright detection is usually used to protect video copyright, such as copyright detection based on spatial color video fingerprints. The video fingerprint based on spatial color is basically generated by using the histogram of a specific area of ​​the picture in a certain time period, and because the color characteristics will change according to different video formats, it will cause the video fingerprint based on spatial color to be inconsistent. It has high anti-noise ability, and the video fingerprint based on spatial color does not have enough anti-noise ability to add trademarks, black...
