模糊聚类分析在数字水印算法设计中的应用

A Watermarking Algorithm Based on Fuzzy Cluster Analysis

基于人眼的视觉系统(HVS),将模糊聚类分析的的基本思想应用于静态图像数字水印算法设计。该算法根据模糊聚类分析思想,结合人眼特性将图像中的像素点进行分类,自适应地确定水印的嵌入位置;并可根据实际用途要求,确定分类数,按不同要求对图像像素进行分类选择。在现有技术条件下即可实现一种乃至多种水印的嵌入,更具广泛应用性。

Combining the human visual system with the image local properties,an spatial domain image watermarking scheme based on fuzzy cluster analysis is proposed.Based on the human visual system,the watermark embedding locations are identified adaptively by applying fuzzy clustering algorithm.The presented watermarking scheme can change the number of categories based by practical requirements.According to different requirements,it can partition image pixels.Don＇t need to new technical,one or more watermark is embedded adaptively the image.It＇s use more extensive and practical.
