Blind Watermarking for Hiding Color Images in Color Images with Super-Resolution Enhancement

This paper presents a novel approach for directly hiding the pixel values of a small color watermark in a carrier color image. Watermark embedding is achieved by modulating the gap of paired coefficient magnitudes in the discrete cosine transform domain according to the intended pixel value, and wat...
