Abstract
In recent years, digital watermarking is a technique for labeling digital images by hiding secret information which can protect the copyright. The goal of this paper is to develop a DCT-based watermarking algorithm for low power and high performance. Our energy-efficient of technique focus on algorithm level processing. We improve Hsu and Wu’s algorithm by using DCT coefficients to pairing blocks directly. The experimental results show our approach not only can reduce a halt of pairing operations required, but also increase the PSNR around 0.2 db.
