摘要

提出了一种利用像素值差分(PVD)法和最小显著性替换法对离散小波变换(DWT)分解后的四个一阶数据进行隐藏的新方法。仿真结果表明，该方法在容量、人眼视觉质量和PVD信噪比方面均优于PVD+3LSB方法、重叠PVD方法和半六边形PVD方法(SH-PVD)。

Wavelet-pixel value differencing technique for digital images data hiding

This paper presents a new technique which uses pixel value differencing (PVD) method and least significant replacement method to hide data in the four first order levels decomposed by discrete wavelet transform (DWT). The simulation results show that the proposed technique gives high performance in terms of capacity, human visual quality and PSNR better than PVD+3LSB method, the Overlapping PVD method and Semi-hexagonal PVD method (SH-PVD).
