[File Format] TS-MPEG2 DL : 0: 目前绝大部分视频数字水印系统是将一个64位-128位的条码嵌入到视频中，而本软件最大特点是可将用户任意指定的一幅120x120的黑白图片(如电子印章)隐藏在一段视频流中。这样做的优点是给用户提供了最大的直观性，同时由于偶们嵌入的是一幅图片而不是一组确定的数字，因此在视频被重编码为mpeg4低分辨率格式、信息大量丢失的情况下，仍可以通过人眼识别出已经非常模糊的图片。-At present, the vast majority of video digital watermarking system is a 64-bit-128 barcode embedded into the video, which is the biggest characteristic of this software can be arbitrarily designated a user 120x120 black-and-white images (such as electronic seals) hidden in a section of video stream. The advantages of doing so is to provide users with the most intuitive, at the same time as a result of embedded偶们is a picture rather than a group to determine the figures, so the video was re-encoding for mpeg4 low-resolution formats, the information a large number of missing cases Under the adoption of the human eye can still identify the picture is very fuzzy.

[Special Effects] A.Blind.MPEG-2.Video.Watermarking.Robust.to.Regula DL : 0: 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 extraction of the watermarks are done in the compressed domain. The mean of the low-frequency DCT coefficients of the video is temporally modulated according to the information bits. To reduce complexity, we embed watermark in the prediction error signals of the B-frames. Experimental results show that the proposed scheme achieves high video quality and robustness to camcorder recording, trans-coding, frame-rate conversion, and geometric attacks on common test videos.

[Wavelet] watermarkcleck-door DL : 0: 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 frequency decomposition [13], to better match the human visual system (HVS Human Visual System). Because the wavelet transform has good frequency characteristics of the locality and multiresolution representation, and, the latest image compression standard- JPEG2000 and video MPEG-7 compression standards have adopted the wavelet transform,
