displacement

使用matlab编写的一个m文件，主要是计算图像的信息熵(Matlab use m the preparation of a document, the main image is the calculation of information entropy)

说明：  g-p算法，分形理论。。。。。。。。。。。。。。。。。。(gp algorithm, fractal theory. . . . . . . . . . . . . . . . . .)

遗传算法 二进制编码 求历代best 显示图形(Successive binary coded genetic algorithm find best display graphics)

2D双向PCA(2D2PCA),二维主成分分析(2DPCA)的实质是对图像矩阵按行进行图像压缩抽取特征,消除了图像列的相关性.(2D bidirectional PCA (2D2PCA), two-dimensional principal component analysis (2DPCA) real image matrix row the Image Compression extraction characteristics to eliminate the correlation of the image column.)

本例子中有40人脸库，详尽的人脸特征提取例子，大家可以参考学习。(This example has 40 face , detailed facial feature extraction example, we can refer to learn.)

一种改进的MUSIC算法，对初学者有用，教学实验(it is a experment for a improved MUSIC, maybe helpful for the learners)

对一幅数字图像采用理想低通、Butterworth低通 、Gaussian低通滤波器进行平滑；对一幅数字图像采用理想高通、Butterworth高通 、Gaussian高通滤波器进行平滑。 (The ideal of a digital image using low pass, Butterworth low-pass, Gaussian smoothing low pass filter on a digital image using the ideal high-pass, Butterworth high-pass, Gaussian high-pass filter smoothing. )

pca用于对TE的过程故障诊断中，很好用的一个程序(pca for process fault diagnosis of TE in a very good program with a)

给出了一些matlab相关函数查询表，还有遗传算法的程序代码(the way of search function of matlab)

利用MAT—LAB对实验数据进行了基于表面轮廓法的三维图像重构，观察不同的平滑领域参数以及轮廓提取阈值对三维重构效果的影响。(In this paper，taking advantage of MATLAB we reconstruct experiment data into three dimension image in the way of feature-based method， and observe the effect of different parameters，such as the size of smooth convolution kernel and the threshold of ex— traction contour，on the quality of three dimension reconstruction)
