高光谱图像的解译是遥感图像应用的一个重要环节。基于线性光谱混合模型的光谱解译技术正在越来越广泛地应用。仿真结果表明，当部分端元参与解译和分区域进行解译时，高光谱图像的解译效果会得到较显著改善。(The unmixing of Hyperspectral imagery is a critical link of the application of remote sensing imagery. Based on linear spectral mixture model, spectral unmixing technology now is being increasingly used. On the basis of it,studying unmixing ways engaged by endmembers in different conditions, comparing and discussing a more effective expression mode of endmembers.)

em算法求解混合高斯模型，适合图像处理中，对象分割(em algorithm Gaussian mixture model suitable for image processing, object segmentation)

极坐标图像转直角坐标图像，相当于球面的展开效果，最好是正方形图像，但是长方形也可以。(POLARTOIM converts polar image to rectangular image)

动态跟踪，边移动边绘制路线。规定经纬度的范围，调用地图的路径算法，求出路径。(Dynamic tracking, while moving to draw lines.Specified range of latitude and longitude, map the path algorithm call, find the path.)

本软件包包括四个程序，主要用于图像处理（图像去噪，图像分割）和模拟退火算法。(This package includes four procedures, mainly used for image processing (image denoising, image segmentation) and simulated annealing algorithm.)

mean shift matlab源码，程序比较简单(mean shift matlab source code, the program is relatively simple)

bag of word,含特征提取，词包(bag of word proggramme)

图像预处理：分水岭分割算法，图像灰度化、高斯平滑、均衡直方图、图像对比度增强(Image Pre-processing: a watershed segmentation algorithm, images of gray-scale, Gaussian smoothing, balanced histogram, image contrast enhancement)

CT图像的平行束重建图像的重建算法，非常高(CT image parallel beam reconstruction image reconstruction algorithm, very high)

实现稀疏表示算法，以lena图像为例，主要用ksvd和omp算法(The sparse representation algorithm is implemented. The Lena image is taken as an example, mainly using the ksvd and OMP algorithms.)
