基于MPEG_7形状轮廓描述编码的数字水印算法 提出了一种基于MPEG-7轮廓描述编码

的视频水印算法.在该算法中,原始视频数据被分割成等帧数的视频组,利用MPEG-7的轮廓

编码计算每个视频帧的主要物体轮廓坐标点集合

-Contour shape descr iption based on coding MPEG_7 Digital Watermarking Algorithm Based on MPEG-7 contour descr iption coding of video watermarking algorithm. In this algorithm, the original video data, such as being cut into frames of the video group, using the outline of MPEG-7 encoding of each video frame the outline of the main objects set coordinates
