Content based color image adaptive watermarking scheme
A color image adaptive watermarking scheme is proposed. To increase the robustness and perceptual invisibility, a model called ICPM (image complexity and perceptibility model) is proposed to analyze the different sub-blocks' properties. A novel technique is proposed for the watermark casting and retrieval by utilizing the properties of the image itself. Experimental results demonstrate the robustness of the algorithm to many attacks, such as JPEG, JPEG2000 and A/D conversion.
