摘要：
In this paper, a novel watermarking scheme based on relationship of Tchebichef Moments is proposed. Firstly, the image is divided into blocks; then the Tchebichef moment's relationship of each block is computed, which is computed rapidly with the help of the look-up-table; finally, the Tchebichef moments of each block are modified to embed watermark. The watermark extraction is the reverse procedure of the watermark embedding and the original image is not necessary in the watermark detection. Experimental results demonstrate that the proposed watermarking technique is robustness to attacks such as JPEG compress, noises, luminance and contrast enhancement and low pass filtering.
