An Improved Video Watermarking Algorithm Based on Relationship

This paper researched an improved digital video watermarking algorithm based on relationship. The algorithm combines the video processing and video coding compression principle which adopts improved Arnold algorithm as well as the technology of the block and carries out a series of replacement process in the DCT coefficients of the video frame YCbCr spatial luminance Y components. Meanwhile, we segment information watermark image, aiming at the information watermark and mark watermark to be double embedded to improve the watermark embedding capacity and computing speed of the algorithm. Simulation results show that this algorithm can keep good invisibility of watermark. It has good robustness to video compression processing and special video attacks which can realize the blind extraction and random watermark detection.
