中文摘要:提出一种彩色图像大容量信息隐藏时域算法。利用人类视觉系统的视见、颜色宽容特性，结合不同的秘密信息位，将彩色图像载体相邻两个像素点红色分量的颜色值作较小的调整，达到在彩色图像载体中隐藏秘密信息的目的。结果证明，该算法信息隐藏容量大，透明性好，健壮性较好，能经受添加噪声、剪切、格式转换等图像处理及攻击。

On Time Domain Algorithm of High-capacity Steganography in Color Image

Abstract:This paper presents a new time domain algorithm of high-capacity steganography in color image. It can be obtained by utilizing the characteristics of visibility curve and color tolerance of HVS (Human Visual System). Complied with different secret message bit, the secret message has been embedded into cover color image through subtle adjustment in adjacent pixels valume of red comonent. The advantages of the proposed algorithm are high-capacity, transparency and robustness. In addition, it is proof against common image processing and attack, such as noise,cut and conversion etc.
