小波域视频水印方案及其篡改证明分析

A wavelet-based image watermarking for tamper-proofing

提出了一种用于篡改证明视频水印方案。该方案采用三维小波变换 ,依据运动检测和人视觉模型自适应的嵌入水印 ,保证隐藏数据的视觉不可见性和一定的容量。此外 ,该算法很好的克服了之前数字水印算法对篡改分析能力弱的缺陷。试验结果表明 。

The paper proposes a 3D\|wavelet\|based video watermarking scheme for tamper\|proofing. Embedding is based on motion detection and utilizes a human visual system, so the invisibility and the capacity are good. The scheme overcomes the limitations of previous schemes which cannot give excellent analysis of tamper. Experiments show that the watermark of the video is invisible and the capability of tamper\|proofing is fine.
