摘要： This paper introduces a blind and efficient digital watermarking algorithm based on the discrete orthogonal tchebichef moment and the spectral characteristics of human vision system. The tchebichef moments can be effectively used as pattern features in the analysis of two-dimensional images. The proposed method for digital image watermarking which is not require the original image for watermarking extraction and detection. The watermark is embed in the mid frequency in the transform domain. Experimental results show that the embedded watermark has good imperceptibility and robustness for the common image processing attacks, such as additive noise, low pass filter, JPEG compression, Cropping, and Rotation.
