For our visible watermarking algorithm, we compute composite coefficients using global and local characteristics of the host and watermark images. We use a contrast-sensitive function and block classification in the discrete wavelet transform domain. 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.
