%X Two watermarking algorithms based on the wavelet zerotree were proposed. Between these two, the embedded watermark was meaning binary image, in order to increase the robustness. These two algorithms introduced hamming coding, chaos modulation and selected these wavelet zerotrees carefully. The simulation results demonstrate that these two algorithms are robust against JPEG compression, image processing and attack such as noise, filtering, cropping etc.
