hough变换检测椭圆的MATLAB程序(hough detection codes to detect shapes in images)

我们的目的是将一个分数拆分成若干个分子是1分母是正整数的分数之和的形式。例如2/3可以拆分成1/2+1/6的形式。这里不考虑顺序，比如1/6+1/2和1/2+1/6相同。 输入p, q, a, n, 其中p/q为分数，对这个分数进行拆分，要求拆分的分数个数不能多于n个，所有分母的乘积不能大于a。求有多少种拆分方法? 输入：最多200组数据。在每行中都有四个数分别表示p, q, a, n，之间以空格隔开，并且满足p,q<=800，a<=12000，n<=7，最后以四个0做为输入的结束。 输入示例: 2 3 120 3 2 3 300 3 0 0 0 0 输出示例: 4 7 (Our aim is to split a fraction into a number of elements is a denominator is a positive integer fraction of the sum of form. For example, 2/3 can be split into 1/2+1/6 form. Not considered here, the order, such as 1/6+1/2 and 1/2+1/6 of the same. Input p, q, a, n, where p/q as a fraction of this split scores require no more than the number of split points n-all the product of the denominator can not be larger than a. How many kinds of demand split method? Input: Up to 200 sets of data. In each line has four numbers indicate the p, q, a, n, separated by a space between, and meet the p, q < = 800, a < = 12000, n < = 7, the end, four 0 as the input end. Input Example: 2,312,032,330,030,000 sample output: 47)

图像数据 的融合就是图像信息处理的综合过程，来自不同的源的图像数据图像信息按一定的准则进行融合，这里是简单的实例源程序，还需要进过修改完善(The integration of image data is image information processing integrated process, from different source of image data of image information according to a certain convergence criteria, here is a simple example source code, but also need to go to revise and improve the)

建立滤波器 如均值 高斯 中值 维纳 可以设置模板(fspecial)

自适应中值滤波与中值滤波算法的比较，说明自适应中值滤波效果好。(Adaptive median filter and median filtering algorithm comparing the adaptive median filter shows good results.)
