摘要: In this paper, the authors propose a new steganographic scheme based on vector quantisation (VQ) and search-order coding (SOC). The capacity of proposed is higher than others VQ quality stego-image acceptive. general, schemes usually 1-bit per block. 2004, Yu et al. to increase 3-bit pair blocks. scheme, utilised multiple codebooks chose combinations blocks, embed secret data. was increased 6-bit identical al.'s scheme.
