Chaotic Watermarking System for Colour images Based on Texture segmentation in Wavelet Transform Domain

In this paper, a novel technique for embedding and detecting a chaotic watermark in the wavelet transform domain for still and colour images is presented. A texture segmentation method of the image in the wavelet transform domain is used in order to identify the coefficients of the textured regions in which the chaotic watermark is embedded. The watermark is detected by computing the correlation between the watermarked coefficients and the watermarked signal. This step is accomplished without using the original image. Simulation results show that it is possible to obtain high fidelity and robustness
