摘　　要：提出了一种基于位面复杂度的高容量可逆信息隐藏方法。首先通过计算低位平面中位平面复杂度分割(BPCS)复杂度筛选出最佳位平面,其次将筛选出的位平面进行实块和非实块划分,对块进行重构组成新的位平面,将辅助信息和秘密信息嵌入,最后通过块置乱、像素置乱和混沌加密对图像进行加密。基于这种算法,一定程度上优化了位平面嵌入选择,可以实现高容量的信息嵌入和图像恢复。A high-capacity reversible information hiding method based on bit-plane complexity is proposed.First,the optimal bit plane is screened out by calculating the BPCS complexity in the low bit plane.Secondly,the screened bit plane is divided into uniform blocks and non-uniform blocks,the blocks are reconstructed to form a new bit plane,and auxiliary information and secret information are embedded.In the reconstructed bit plane,the image is encrypted by block scrambling,pixel scrambling and chaotic encryption.Based on this algorithm,bit plane embedding selection is optimized to a certain extent,which can achieve high capacity information embedding and image restoration.
