%X Embedding capacity is one of the important factors that affect the information hiding perfomance.An improved information hiding scheme for VQ-compressed index map images based-on joint neighboring coding(JNC) technique is proposed to increase the embedding capacity.The proposed method embeds secret data by using the difference values ranging between the current VQ-compressed index and its four neighboring indices.Experimental results show that the proposed method increases the embedding capacity significant...
