| 摘 要： | 视频水印技术按照水印与视频的结合形式,分为压缩域水印和原始视频水印。压缩域水印可以很好地利用视频序列在时间上的冗余,但嵌入水印信息量较小;原始视频水印技术没有充分利用视频序列时间冗余度,但嵌入水印的信息较多,耗费时间较多。HG算法可以不解码视频而快速嵌入水印信息,但嵌入容量有限。本文改进HG算法通过分析非关键帧运动矢量,选择关键帧嵌入位置,使得在压缩域嵌入水印时,水印嵌入速度和嵌入量有较大幅的改进。

| Abstract: | 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. |
