Abstract: Digital video watermarking is an efficient way of copyright protection. A robust watermarking was proposed that ccording to the video features using the evolutional method of video image classification processing, suitable for video performance and human visual characteristics of video watermarking, and put forward a kind of using Bees evolutional algorithm for video image classification processing of video watermarking algorithm. All the key frame numbers are converts to a binary matrix after data transformation. At last the binary image is produced. From this, the watermarking image reflects the video’s features, so it is effective to resist the watermark copy attack.

Abstract: This paper according to the video features using the method of evolution of video image classification processing, suitable for video performance and human visual characteristics of video watermarking, and put forward a kind of using artificial swarm evolution algorithm for video image classification processing of video watermarking algorithm, improve the watermark performance.

Abstract: A variety of video watermarking algorithm is not rare. But the connection of watermarking algorithm and video feature is a completely new field. This algorithm attempts to generate the watermarking image based the number of video’s key frames. All the key frame numbers are converts to a binary matrix after data transformation, at last the binary image is produced. According to those steps, the watermarking image reflects the video’s features, so it is easy to resist the watermark copy attack.

Abstract: The algorithm applied to video watermark based on the property of the video is rare recently . This article brings the video property and HVS into the video watermark，gives an new algorithm， improve the capability of the watermark.
