【摘要】 提出了一种基于差错控制的视频图像数字水印新方法,该方法是在H.263视频编码I帧图像的变换域中嵌入水印,而且在水印的提取上实现了盲检功能。新算法与视频编码压缩标准有很好的兼容性,实验结果说明了所提出视频水印新算法的有效性。更多还原

【Abstract】 A new video watermarking algorithm based on error control is proposed, which embeds watermarks into DCT coefficients of I frames in H.263 coding streams. Additionally, the proposed algorithm is able to detect watermarking without original image, and is compatible with H.263 standard. Experimental results show the efficiency of the proposed video watermarking newalgorithm.更多还原
