Adaptive 2-D Color Image Watermarking Based on DCT
By discrete cosine transform（DCT）, still image compression coding technique, and human visual system （HVS）, the2-dimensional digital watermark （gray image） is embedded adaptively into the color host image. Experimental results show that the proposed watermarking scheme is invisible and robust against various signal processing such as cropping, compression, filtering, noise adding, image enhancement, and mosaic.
