A reversible steganographic scheme for VQ indices based on joint neighboring coding

作者：

Highlights：

• 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.
