读取envi的img格式的高光谱文件，是matlab对其进行处理高光谱图像，是env和matlab相同(Read envi img format hyperspectral file, is matlab to deal with hyperspectral images, is the same as env and matlab)

图像的中值滤波源码例程程序结合易语言数值计算支持库和图像格式转换支持库，调用正态分布图像处理模块实现图像的中值滤波功能。(Image median filtering routine program combined with easy language source numerical support libraries and image format conversion support library , call the normal image processing module median filtering images.)

线性非局部均值滤波器用于图像处理中的去除噪声平滑图像，能够较好的保持图像的边缘(Linear non-local mean filter for image processing to remove noise smoothing of images, to better maintain the image edge)

gif图片转换成jpg文件格式 实例源码

基于LDA的人脸识别技术，从ORL数据库读数据，然后从中取一部分进行训练，一部分进行测试。(This code is LDA base face recognition programme. It reads nots faces from ORL database and the rest (noc-nots) are used as test. LDA_Performance shows the recognition performance. )

一个简短的计算图像信息熵的程序，对于初学IDL的开发者来说，有一定的借鉴作用(A brief image information entropy calculation procedure, IDL for beginner developers who have a certain reference)

该程序是对输入的数字图片进行特征提取，以得到图片对应的向量，从而为下一步的识别提供帮助。(The program is to input the number of picture feature extraction in order to obtain the corresponding vector images, so as to identify the next step to help.)
