说明：  这是一个有关frft的matlab的程序，请好好利用吧(a programm about frft,please take full use of it)

说明：  这里面包含两个程序段，是学习SIMULINK的基础程序，很有借鉴意义，不学习的就不要浪费时间了(This procedure consists of two paragraphs which is the basis of SIMULINK learning process, referential significance, not to learn not to waste time on)

一种基于基因遗传算法和支持向量机的回归算法(Regression algorithm based on genetic algorithm and support vector machine)

说明：  最小外接矩形，根据面积和周长判断。实现图象处理的工程计算。( Compute the minimal bounding rectangle of points in the plane usage: [rectx,recty,area,perimeter] = minboundrect(x,y,metric) arguments: (input) x,y- vectors of points, describing points in the plane as (x,y) pairs. x and y must be the same lengths. metric- (OPTIONAL)- single letter character flag which denotes the use of minimal area or perimeter as the metric to be minimized. metric may be either a or p , capitalization is ignored. Any other contraction of area or perimeter is also accepted. DEFAULT: a ( area ) )

经典的基于短时能量和短时平均过零率的双门限检测方法(Classic double threshold detection method based on short-time energy and short-time average zero crossing rate)

matlab的蚁群算法边缘检测方法。代码可以给需要的人学习(ant colony algorithm for edge detection in matlab. The code can be to those who need to learn)

it is a matlab file.it is used to do some basic rd in matlab.

這是一個可以自動尋找图像中的長方形, 正方形, 圓形, 菱形的程式(1- Read the RGB (colored) image in from user. 2- Convert image from (RGB) colored to gray image. 3- Threshold the image (convert gray image to binary image). 4- Invert the binary image (in order to speed up the time of processing). 5- Find the boundaries concentrate. 6- Determine shapes properties (ratio of dimensions, roundness). 7- Classify shapes according to its properties. )
