SVD-Based Image Water Marking

摘要: Advances in Internet technology have considerably facilitated the acquisition, representation, storage and distribution of images digital format. These advances, however, made unauthorized manipulation reproduction original an easy process. Consequently, design development effective image copyright protection methods become necessary. Recently, watermarking has emerged as a major to prevent illegal malicious copying by embedding unnoticeable information into content. In this paper, we propose imperceptible robust algorithm. The algorithm is based on cascading two powerful mathematical transforms; Discrete Wavelet Transform (DWT) Singular Value Decomposition (SVD). Combining transforms compensates for drawbacks each other, resulting very watermarking. Simulation results demonstrated effectiveness our proposed
