CDMA-based watermarking resisting to cropping


In this paper, we propose an image watermarking algorithm in DWT domain with self-synchronization, focusing on resisting to cropping attack. In embedding, the CDMA encoded watermark, concatenated by the synchronization code, is embedded into the selected DWT coefficients of the original image. During the oblivious watermarking detection, the corresponding… (More)
