| 摘 要： | 基于人类视觉系统的纹理掩蔽特性,提出一种基于模糊C-均值(FCM)和自适应遗传算法小波域彩色信息隐藏算法。首先对彩色载体图像Y分量实施整数小波变换;然后结合视觉纹理特性,对低频进行FCM聚类分析,将其分成3类:平滑区、纹理区、边缘区,并在不同的区域确定不同的嵌入强度和位置;最后,利用自适应遗传算法对logistic混沌映射的初值进行寻优,使其找到合适的初值,从而使秘密图像对载体图像的影响较小。实验结果表明:该方法不仅具有较好的透明性,而且在嵌入量方面也有很大的提高。

| Abstract: | As for the texture sheltering characteristics of the human visual system,the paper proposes an FCM-and AGA-based wavelet domain colour information concealing algorithm.At first the scheme executes integer wavelet transform on the Y coefficient of the colour host image.Next in accordance with visual texture characteristics it executes FCM clustering analysis to partition low frequencies into three areas: the smooth area,the texture area and the edge area.Different embedding strengths and locations are define... |
