Analysis Watermark Embedding Position in H.264 Compression Video
Xie Jin-ba · 2014
Video watermarking technology combined form in accordance with the video watermark,the watermark into the compressed domain and original video watermark. Compressed domain watermarking a video sequence can be a good use of the redundancy in time,but little information is embedded watermark; original video watermark underutilized temporal redundancy of video sequences on the basis of the watermark information can be embedded more,time consuming. H G method can not decode the video quickly embed watermark information,the program in the H G algorithm is based on the analysis of non- key frame motion vector selection key frame embedding locations,such that when the compressed domain embedded watermark,the watermark embedding rate and the doping amount of a substantial improvement.
