A Chaos-Based Video watermarking in Wavelet Domain
A novel vide o watermarking scheme based on chaotic maps and wavelet transform is proposed in this paper. The algorithm encrypts a logo image as a watermark signal by bit xor’ing the pixel values of logo and a chaotic map, thus the security of the proposed scheme will be increase...
