摘要

本文研究了H.264标准中存在拉普拉斯噪声的加性视频水印方法。在某些应用中，由于某些像素或帧的某个区域的损失，我们采用拉普拉斯噪声而不是高斯噪声。在变换域中进行嵌入;同时给出了一种最优解码器和一种次优解码器。仿真结果表明，所提出的水印方案具有良好的性能和足够的透明度，可以满足水印应用的要求。

Optimum decoder for an additive video watermarking with Laplacian noise in H.264

In this paper, we investigate an additive video watermarking method in H.264 standard in presence of the Laplacian noise. In some applications, due to the loss of some pixels or a region of a frame, we resort to Laplacian noise rather than Gaussian one. The embedding is performed in the transform domain; while an optimum and a sub-optimum decoder are derived for the proposed Laplacian model. Simulation results show that the proposed watermarking scheme has suitable performance with enough transparency required for watermarking applications.
