Abstract :
Watermarking algorithm based on wavelet transform is a main field in digital watermarking study. With watermarking property, the paper investigates the distributed feature of the wavelet coefficient and analyzes the effect of typical attacks to the wavelet coefficient. Through the experiment of different texture and gray images, the paper analyzes the relation between embedding intensity and watermarking invisibility.
