Abstract
The authors use a visible watermarking algorithm for digital rights management that computes composite coefficients using global and local characteristics of the host and watermark images. They also use a contrast-sensitive function and block classification in the discrete wavelet transform domain for a better visual effect. The original and watermark images are divided into different blocks and classified based on visual masking. Experiments indicate that this approach provides a better visual effect than other schemes.
