Abstract
A robust wavelet-based blind technique for color image watermarking is proposed denoted as color image watermarking using self-embedded color permissibility (CIW-SECP) is proposed. CIW-SECP technique is based on embedding two watermarks in a spread-spectrum fashion in the
U and
V planes of the
YUV color space. The watermark weights are generated based on the so-called “color permissibility” of the
U and
V planes. These weights are generated and self-embedded in the relative
U and
V planes based on the color characteristics of the image under question. Experimental results have shown that the CIW-SECP technique exhibits very high imperceptibility (PSNR∈[71.21–85.95]
dB) as well as superior performance against most prominent attacks.
