摘要： In this paper, we propose two reversible information hiding schemes based on side-match vector quantisation (SMVQ). In 2006, Chang et al. proposed a data-hiding scheme based on SMVQ coding. In order to increase both the image quality and the embedding capacity, we improve their method by embedding multiple secret bits into a block and finding out the second selected codeword from the full codebook. In addition, we propose another reversible information hiding scheme whose output is a pure VQ index table. The weighted bipartite graph is used to model our scheme and the matching approach is used to find out the best solution. Compared with Chang et al.'s scheme, we have higher visual quality in the experimental results. 出版者： Taylor & Francis 出版日期： 2013-02-01 出處： The imaging science journal, 2013-02, Vol.61 (2), p.195-203 資源來源： EBSCOhost Academic Search Premier 版權： RPS 2013 2013 識別號： ISSN: 1368-2199 識別號： EISSN: 1743-131X 識別號： DOI: 10.1179/1743131X11Y.0000000031
