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)

统计颜色直方图的matlab程序,解压缩后可以直接在MATLAB环境中运行(Color histogram statistics of the matlab program, unzip it directly in the MATLAB environment)

很简单的基于颜色的图像检索系统，闲时做的(Very simple color-based image retrieval system at leisure to do the)

先进行图像的预处理，采用中值滤波，梯度增强。基于边缘帧差法实现前景检测(first image preproceing，the median filtering，grdient enhancement。based on edge detection method of frame to realiase prospect)

opencv图像库函数集，有关最新的opencv新增函数的应用(opencv functions)

用matlab实现不规则光照下自适应阈值的前景背景分离算法。文件里面附测试图像。(Matlab implementation to use irregular light of the prospects for adaptive threshold background separation algorithm. Test image files attached inside.)

说明：  图像检测，目标检测简单来说就是找出图像中的目标并给定目标的位置，一般用矩形框定位出目标(In image detection, target detection is simply to find out the target in the image and give the location of the target. In general, the rectangular box is used to locate the target)

说明：  用python实现傅里叶的快速变换，实现与传统傅里叶变换不同的快速傅里叶变换，也使用了一些图形界面设计(Using Python to realize the fast Fourier transform, which is different from the traditional Fourier transform, and also using some graphic interface design)

压缩文件中的代码可以读取图片并计算绿色植被的归一化植被指数，直接在IDL中打开即可使用(The code in the compressed file can read pictures and calculate the normalized vegetation index of green vegetation,and you can open it directly in IDL and use it.)

图像傅利叶变换源码程序，结合易语言位图操作支持库，通过傅利叶公式的计算变化图像。(Fourier transform image source program , combined with easy language support library bitmap operations , by calculating the Fourier formula change images.)
