Abstract
This paper proposes a scheme that combines QIM and contourlet in image watermarking. Contourlet is a new transform that able to capture the directional edges and contours superior, but it also requires host image when extracting watermark. Through two embedding stages, our algorithm allows blind extraction, highly robust for different attacks on the watermarked image.
