Abstract

Considering the image compressibility and the error allowance of decoded image, this paper presents a high-capacity image watermark method based on fractal compression in the wavelet transform domain. Fractal compression technique is used to encode a gray image and the fractal codes are embedded into the wavelet coefficients of the gray image according to well-connected watermark algorithm. After watermark extracted, the gotten codes may be decoded into an image identified to owner. Through the validation of the experiments, this watermark method has good performance of data compression.
