raytracing program for seismic forward modeling

这是一个Knn分类算法的Python实现，Matlab中有类似的函数(knn classifer)

使用Matlab编程实现GMM算法,不调用已有函数库，对大量点进行分类(LM algorithm using Matlab programming, do not call the existing library, a large number of points to classify)

对读入的图片做霍夫变换，识别出图片中的直线并输出。(Do the Hough Transform to the input image, that is to detect lines in the input image, and output those lines.)

说明：  本书对以Matlab为基础，从数字信号处理及图像处理的原理和算法入手，着重阐述用Matlab实现数字信号处理及图像处理的重要算法。(Book, Matlab-based, from digital signal processing and image processing theory and algorithms to start, focusing on the digital signal processing using Matlab and the importance of image processing algorithms.)

运用matlab来进行最大似然方法实现符号定时同步和载波同步仿真。(use Matlab to the maximum likelihood method Symbol Timing and Carrier Synchronization simulation.)

基于LS-SVM的一个预测代码。对实际数值进行预测得到图像(LS-SVM based on a prediction code. Predicted value for the actual image)
