A DCT_SVD domain watermarking algorithm for digital image based on Moore-model cellular automata scrambling

Abstract

A DCT_SVD field watermarking algorithm for digital image based on Moore-model cellular automata scrambling is proposed in this paper. Firstly, Moore-model cellular automata with chaotic characteristics is used to disorder the original mark. Then the original carrier image is carry on 8×8 block discrete cosine transform (DCT), where low frequency… (More)
