In this paper, we proposed a novel blind digital image copyright protection scheme based on Steerable pyramid transform (SPT) and visual cryptography (VC). Unlike traditional watermarking schemes, the proposed method does not alter the original image by embedding the watermark image. Steerable pyramid transform is performed on the original image, and the(More)
— In this paper, we present a new, robust digital watermarking scheme for ownership protection. The scheme is based on Steerable Pyramid (SP) and discrete cosine transform (DCT) using Pearson product moment correlation. During the process of watermark embedding, SP is performed on original host image, and corresponding oriented sub-band is selected to carry(More)
