MATLAB

ENVI二次开发常用功能代码，包括大气校正、定标、分类(监督+非监督)、裁剪、镶嵌等(ENVI secondary development commonly used function codes, including atmospheric calibration, calibration, classification (supervision+ unsupervised), cutting, mosaic, etc.)

这是一个（原创的）用matlab做成的维纳滤波器程序，可以直接运行，对于初学数字信号处理的各位有不错的帮助。((original) using Matlab caused by Wiener filter procedures, and can directly run for the beginner in digital signal processing you have any good help.)

说明：  ENVI格式多光谱数据批量求平均值并保存成tif格式文件输出(Batch average of ENVI multispectral data and save it as TIF file output)

平时工作中常会遇到需要处理图片的工作，这个是判断并修改图片分辨率的python方法。(Usually work the Central Standing Committee met to deal with the work of the picture, this is a python method to determine and modify the image resolution.)

人脸检测与跟踪，我的毕业论文，使用我自己改进的ADABOOST和CAMSHIFT算法,附带我的毕业论文,opencv1.0或以上自己配置(face detection use adaboost and camshift algorithm，relevant paper enclosed，OPENCV1.0 is necessary)

输入图片的一阶矩、二阶矩、三阶矩。颜色空间可以在计算前更改( the first moment, second moment and third moment of the picture)

去雾算法halcon代码实现

matlab的关于图像处理的一些简单源代码，大家可以试一试，欢迎下载(Matlab on image processing some simple source code, you can try downloading welcome)

sift算法在cv领域的重要性不言而喻，该作者的文章引用率在cv界是number1.本篇博客只是本人把sift算法知识点整理了下，以免忘记。本文比较早的一篇博文opencv源码解析之(3)：特征点检查前言1 中有使用opencv自带的sift做了个简单的实验，而这次主要是利用Rob Hess的sift源码来做实验，其实现在的opencv版本中带的sift算法也是Rob Hess的，只是稍微包装了下。 下面来做下试验,试验sift代码采用Rob Hess的代码，opencv目前版本中的sift源码也是采用Rob Hess的。代码可以在他的主页上下载：http://blogs.oregonstate.edu/hess/code/sift/ 这里我下载的是windows版本的，并采用Qt做了个简单的界面。(sift algorithm is self-evident the importance of the cv field, the author of the article referenced in the cv sector is number1 this blog I just sift algorithm knowledge compiled under, so as not to forget. This article compares the earlier blog post opencv source code analysis (3): check the preface of the feature points 1 the opencv bring their own sift to do a simple experiment, but this time Rob Hess' s sift source to experiment. In fact, with the opencv version sift algorithm is Rob Hess, only slightly packing the next. Below to do the next test, test sift code using the code of Rob Hess, sift source opencv version of Rob Hess. The code can be downloaded on his home page: http://blogs.oregonstate.edu/hess/code/sift/ here I downloaded the windows version, and using Qt to do a simple interface.)

用哈夫曼算法对图像进行压缩， 1.颜色模式转换及采样； 2．DCT变换（离散余弦变换）； 3．量化；4．编码（有算术编码和哈夫曼编码两种，这里采用哈夫曼编码）
