数字水印技术是近年来图像保护技术研究领域的一个热点,本文提出了一种基于小波变换的图像数字水印嵌入算法的Matlab实现。实验结果表明,该算法具有较好的视觉效果和透明性。 (Abstract　The digital watermarking technology is the most active topic in image protecting recently.In this paper, a digital watermarking algorithm based on Wavelet transform is proposed,and give ou the program of this algorithm by MatLab.The experimental results demonstrate that the method possess good vision effect and transparence. Keywords　Image protecting　Wavelet transform　Digital　Watermarking　Matlab )

K-mean均值算法是给定类的个数K，将N个对象分到K个类中去， 使得类内对象之间的相似性最大，而类 之间的相似性最小。 Kmean处理图像的matlab文件 (K-mean algorithm is given class means the number of K, K to N objects assigned to a class, making class similarity between objects within the maximum, while the similarity between class minimum. Image processing matlab file Kmean)
