In this paper, a wavelet domain robust watermarking technique for still images is presented. Watermark message encoding is accomplished based on iterative error correction codes with reasonable decoder complexity, followed by the codeword spreading over the whole image. Unlike the traditional technique, the proposed method utilizes the statistical property of a certain local area of an image in DWT domain for the watermark embedding and extraction. To minimize the perceptual degradation of the watermarked image, we propose an image compensation strategy (ICS) to make the watermark perceptually invisible. Experimental results demonstrate the robustness of the algorithm to many attacks, such as A/D and D/A processing, rescaling, and lossy compression.
