Abstract: The digital image, watermarking is studied for both copyright protection and content authentication, and needed to be better able to survive image processing operations and to be less degradation of image quality. The results for the gray scale images were presented with the methodology of watermarking by discrete wavelet transform using adaptive quantization in the previous works. The results of this methodology processed to the color images were reported in this paper.
