“…To improve the invisibility, color distances corresponding to embedding distortions are computed in the L*a*b* colorspace. Then, this method was improved in [ 6 ] by adding the mark directly into the L*a*b* colorspace. In other words, the embedding is processed in the color domain and takes advantage of the low sensitivity of the HVS to perceive small color differences.…”

In this paper, we address the problem of the use of a human visual system (HVS) model to improve watermark invisibility. We propose a new color watermarking algorithm based on the minimization of the perception of color differences. This algorithm is based on a psychovisual model of the dynamics of cone photoreceptors. We used this model to determine the discrimination power of the human for a particular color and thus the best strategy to modify color pixels. Results were obtained on a color version of the lattice quantization index modulation (LQIM) method and showed improvements on psychovisual invisibility and robustness against several image distortions.

In this paper a region based color image watermarking algorithm is presented. The objective of the method is to embed a particular message in each region of interest (ROI) in the image. The embedding message has to be detected after image manipulations such as cropping, rotation and color JPEG compression. As a basis for the watermarking, a segmentation algorithm is used. Based on the extracted regions, characteristic features are estimated by using shape information. The embedding message is synchronized with each ROI on each color component Y, Cr and Cb. To embed information non-rounded DCT coefficients are watermarked. Experimental results show the performance of the algorithm against spatial and frequential attacks.
