实现图像分割功能的matlab程序，有效分离指纹前景和背景，方便下面的操作(Image segmentation function of the matlab program, effective separation of the foreground and background, to facilitate the following operations)

说明：  人工神经网络BP算法源代码与演示程序，为神经网络是实例(Artificial neural network BP algorithm source code and demo program, for neural network is the instance)

分数阶傅里叶变换 Matlab仿真实现 单分量的LFM信号的检测和参数估计( Fractional Fourier Transform Matlab simulation to achieve a single-component LFM signal detection and parameter estimation)

此程序是基于哈夫变换的一个圆形检测程序，给定检测边界和半径估计值的范围，此程序能返回圆在图片中的圆心坐标和半径大小。(This program is based on the Hough transform of a circular testing procedures, testing boundaries and radius of a given range of estimates, this procedure can return to the center of the circle in the image coordinates and radius.)

本程序为使用剩余矩形排样法排样的矩形件排样程序，应用matlab软件编程制作。程序能够根据用户输入的排样方案对给定的25块矩形件在宽为15的板材中进行排样，并绘制矩形件排样图。(This procedure is used to drain the remaining rectangular nesting nesting kind of rectangular pieces of the program, application software programming matlab produced. Program can be ranked based on user input for a given sample solution 25 in the width of a rectangular piece of sheet 15 in the nesting, and draw a rectangular piece nesting map.)

Image comparison in a database based in grayscale histogram and using lloyd algorithm. (algo1 index image, algo2 compute the distance betwen two images, algo3 and algo4 make up all togheter)

自己编写的快速傅里叶变换程序，针对一维信号(Fast Fourier transform to write your own program, for one dimensional signal)

Regularization Tools version 4.0 for Matlab 7.3

该程序是一个较简短的程序，主要读取磁共振fid信号，显示波形(The program is a relatively short procedure, the main reading magnetic resonance fid signal waveform display)
