说明：  刚刚接触图像检索的同学，对基于特征的图像检索还没有什么概念，利用这个小的程序（里面附有图像和实例）感受一下过程，对于继续研究很有帮助。(Contact with students just image retrieval, the feature-based image retrieval has no concept of, take advantage of this little program (inside with images and examples) feel the process and continue to study for the useful.)

说明：  提取图像的GLCM矩阵，并计算出Haralick建议的14个特征值(Extract images GLCM matrix, and calculate the 14 Haralick features of the proposed values)

论文：基于二维图像的三维重建的研究。本文是基于二张二维图像，然后进行三维重建，是用matlab程序实现的。文中详细介绍了每一步的现实方法和原理。(Thesis: Based on two-dimensional image reconstruction of three-dimensional. This article is based on two Zhang Erwei image, and then three-dimensional reconstruction is achieved using matlab program. Described in detail every step of the reality of methods and principles.)

matlab内置软件包,提供一些拟合，特殊函数等(matlab built-in package that provides some of the fitting, special functions, etc.)

用于检验两个时间序列是否具有格兰杰因果关系(Used to test whether two time series have Granger causality)

本程序针对高通公司开发的IS-95通信系统，是一个相对完整的IS-95前向信道的仿真源程序，包括Viterbi编码，数据调制，基于RAKE接收机的解调，实现软判决输入的Viterbi译码等模块，并包括有误码率的计算和性能仿真显示。 (The procedure developed for Qualcomm IS-95 communication system, is a relatively complete IS-95 forward channel simulation source code, including Viterbi coding, data modulation, demodulation based RAKE receiver to achieve soft decision input Viterbi decoding modules, and includes a bit error rate performance computing and simulation show.)
