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)
In this paper, a novel watermarking scheme is proposed by embedding a gray-scale watermark into gray-scale images. The proposed scheme is a Hybrid watermarking algorithm based on singular value decomposition (SVD) and Steerable Pyramid (SP) wavelet transform. The robustness of the proposed method is evaluated by executing various image processing attacks.(More)
Digital image watermarking techniques for copyright protection are used by many people to protect their images from others. The goal of this work is to propose a new digital watermarking technique, which depends on the steerable pyramid decomposition transform. By taking into consideration invisibility and robustness, the watermark is embedded several times(More)

Abstract Most of the watermarking schemes that have been proposed until now are based on DCT, DFT, and DWT transformations. For this reason , this paper presents a new robust(More)
