Robust watermarking algorithm of color image based on DWT-DCT and chaotic system

Abstract

This paper elaborates an algorithm of robust image watermarking schema which is focus on embedding RGB watermark into RGB color image. The algorithm is based on discrete wavelet transform (DWT), discrete cosine transform (DCT) and chaotic system. The schema applies a self-adapted watermark image, according to the color image R, G, B components of the… (More)
