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

Abstract—Based on the observation that low-frequency DCT
coefficients of an image are less affected by geometric processing,
we propose a new blind MPEG-2 video watermarking algorithm
robust to camcorder recording. Both the embedding and

小波变换域图像水印算法是一种对图像多尺度的空间频率分解[13],能更好地与人类视觉系统(HVS Human Visual System)相匹配。由于小波变换具有良好的时频局部性和多分辨率表示的特点,而且,当前最新的图像压缩标准——JPEG2000 和视频的MPEG-7 压缩标准都采用了小波变换,-The wavelet transform domain image watermarking algorithm is a multi-scale image of the spatial frequ
