Abstract
Compression on a watermarked image can significantly affect the detection of the embedded watermark. To show that a particular watermarking scheme is robust against compression, simulation is often relied upon. In this paper, we investigate this problem analytically. We first characterize the noise introduced by JPEG compression. We then propose a maximum a posteriori (MAP) detector, analyze its performance, and demonstrate that it has superior performance over the correlation detector
