kmeans

幻方的构造及幻方实现的程序，对于其他双偶阶的幻方，只是在作‘*’标记时，应把4N阶方阵分为N个4阶方阵进行标记，数字填入仍按从左到右，自上而下填入(Magic Square and the magic square implementation procedures for other pairs of even order magic square, just as ' *' mark should be put into N 4N square matrix of order 4 squares labeled, digital still fill left to right, top to bottom fill)

基于有限高斯混合模型的EM算法的源程序代码，里面有实验报告和运行结果。 (based on finite Gaussian mixture model of the EM algorithm source code, which has run reports and experimental results.)

k均值聚类，类数可以自行指定，输出散点图，红色十字为聚类中心(K-means clustering, the class number can be specified on its own, the output scatterplot chart, and the Red Cross for clustering center)

用comsol做声固耦合的例子，例子的内容是声子晶体的投射系数，对用comsol来计算声子晶体的初学者很不错(Coupled with comsol said anything solid examples, examples of the content is the projection coefficient of phononic crystals, the phonons with comsol to calculate the crystal is very good for beginners)

该压缩包里包括了一幅图像的位平面解，即一幅灰度图像可以分成八个位平面。利用它可以转化到彩取色图像中去，很有用处的。(The bag includes a compressed image bit-plane solution, that is, a gray image can be divided into eight bit-plane. Use it can be transformed into the color check color images, and useful.)

可以Raw格式图片(you can open raw file with the .m code.)

读入语音信号并对其进行dct变换进行压缩变换的matlab程序(Reading the speech signal compression transform Matlab procedures and dct transform)

实现了Thien在他的文章《secret image sharing》中提出的（r，n）门限秘密图像分存方案。 (Thien in his article " secret image sharing" (r, n) Door Threshold Secret Image Sharing Scheme.)

小波去噪算法，包含多种小波去噪去噪，强制去噪、软阈值去噪、硬阈值去噪(Wavelet denoising algorithm that contains a variety of wavelet denoising denoising forced denoising, soft thresholding and hard threshold denoising )

该程序是发表在IEEE上的经典直线提取论文“Extracting Straight Lines”的源代码实现，对计算机视觉、模式识别和信息提取等领域的科学研究人员具有极其重要的参看意义。建议下载学习和适用。(The program is published in the IEEE paper on the classic straight-line extraction " Extracting Straight Lines" the source code implementation of computer vision, pattern recognition and information extraction and other areas of scientific researchers see an extremely important significance. Recommended to download to learn and to apply.)
