A Watermarking Algorithm Based on Wavelet and Cosine Transform for Color Image
Wei-Min Yang, Jin Yan Zheng · 2009
In this paper, we propose a watermarking algorithm for color image based DCT and DWT. A binary image as watermark is embedded into green component or blue component of color image. The algorithm can satisfy the transparence and robustness of the watermarking system very well. The experiment based on this algorithm demonstrates that the watermarking is robust to the common signal processing techniques including JPEG compressing, adding noise, low pass filter, and mosaic.
