用Matlab实现基于核函数的C均值聚类图像分割，实验好，好用(Using Matlab implementation of kernel-based C-means clustering image segmentation, experimental is good, easy to use)

聚类有效性指标,比较全，功能比较强大，是学习聚类的好工具(Clustering Validity Indices)

说明：  该代码能实现图像缩放功能，简单，容易理解(The code to achieve the image zoom feature, simple, easy to understand)

视频中静态目标背景下运动的物体的前景提取算法的实现。(The foreground extraction algorithm for moving objects in static background is implemented in video.)

本程序是一幅512*512的lena.raw图像进行快速DCT和其逆变换，整个程序均调试通过，是在C语言环境下编写的，在整个关于快速DCT的源码中，本代码可以说是集大成者，很值得一看。(This procedure is mainly of a float or double type of data, rounding, the float data can be positive or negative, can be, take the whole principle of rounding.)

人体脑信号波形检测与分析,包含自相关,功率谱分析的方法(Human brain signal detection and analysis, including autocorrelation, the method of power spectrum analysis)

通过小波阈值去噪，选取db5小波进行6层分解，对心音信号进行去噪(By wavelet thresholding, select db5 wavelet decomposition of six layers of the heart sound signal de-noising)

基于彩色图像实现的DCT变换域图像数字水印算法。(Color images based on the realization of the DCT transform domain image watermarking algorithm.)

一幅真彩色图像的小波去噪方法实例。通过对一幅真彩色图像的RGB三个方面分别处理，把处理后的结果结合得到。(A true color image examples of wavelet denoising method. Through a true color image of the RGB three aspects dealt with separately, the results of the combination to be processed.)

说明：  提取图像中的模式噪声，是先使用滤波器后再进行提取的(To extract the pattern noise in an image, a filter is used first and then the noise is extracted)
