Robust RGB color image watermarking scheme based on DWT-SVD and chaotic system

This paper presents a robust image watermarking scheme for embedding gray scale watermark into RGB color image. The presented method is based on discrete wavelet transform (DWT), singular value decomposition and chaotic system. DWT and SVD are separately applied on three color planes (R, G and B) of original color image and watermark image for embedding and extracting processes. DWT and SVD techniques are used in the proposed watermarking scheme...
