Video Watermark Algorithm Study of Shot Segmentation Based on Motion Vector

Abstract

In order to solve the copyright protection problem of multimedia videos, a kind of video watermark algorithm based on motion vector for shot segmentation is proposed. The algorithm put forward in this paper can accurately implement video shot segmentation, extract key frames, and search for the proper watermark embedded position. The timeliness of watermark embedding is high, its imperceptibility is favorable, equipped with anti-gaussian noise, frame deletion, frame exchange and other robustness of attack. And it also has smaller effects on code rate, which can be perfectly applied into the copyright protection of videos.
