LSB嵌入方法的载体图像区域选择

Region selection in LSB embedding of steganography

针对在密写术中的LSB(最低有效位)嵌入方法会对载体图像的平滑区域造成破坏,导致载体图像的不可感知性下降和不可检测性降低的问题,提出了一种区域选择方法,避免载体图像的脆弱区域在LSB嵌入操作中被破坏。通过实验证明了,该方法可以有效改善视觉不可感知性,提高对LSB嵌入操作的不可检测性。

This paper addresses the problem of affecting smooth regions in LSB （Least Significant Bit） embedding method in steganography.Smooth regions in cover image are not appropriate for applying LSB embedding.The method to make regions selection on the cover image finding suitable regions is proposed.By counting on each pixel to decide if it is a pixel to be protected.The experimental results show the proposed method can improve the visual imperceptibility and promote the undetectability of the LSB embedding method.
