A reversible steganographic scheme for VQ indices based on joint neighboring coding
A novel reversible steganographic scheme for VQ indices based in joint neighboring coding is proposed. The proposed scheme can embed n secret bits into one VQ index, where n=1, 2, 3, or 4. The proposed scheme can provide high embedding rates, low bit rates, and high embedding efficiencies.
