Abstract

An adaptive steganographic scheme is proposed in this paper. The adaptive quantization embedder is introduced and employed by block-wised fashion. We also constructed contrast-correlation distortion metric to optimally choose quantization steps for image blocks to guarantee more data being embedded in busy areas. Different form existing methods, our scheme embeds the AQE parameters together with message bits into the cover image by difference expanding algorithm. Simulation experiments show the proposed scheme can provide a good trade-off between the perceptibility and the capacity.
