Description: 所谓边缘就是指图像局部亮度变化最显著的部分，它是检测图像局部变化显著变化的最基本的运算。对于数字图像，图像灰度灰度值的显著变化可以用梯度来表示，以边缘检测Sobel算子为例来讲述数字图像处理中边缘检测的实现-Edge refers to the so-called partial image brightness changes in the most notable part of it is to test local image change significantly change the basic arithmetic. For digital images, image intensity values of gray significant gradient changes can be expressed as to Sobel edge detection operators as an example to tell the story of digital image processing to achieve the Edge Detection

Description: 矩阵中的每一个元素称为像元、像素或图像元素。而g(i, j)代表(i, j)点的灰度值，即亮度值。
由于g (i, j)代表该点图像的光强度（亮度），而光是能量的一种形式，故g (i, j)必须大于零，且为有限值，即： 0＜=g (i, j)＜2n。
用g (i, j)的数值来表示(i, j)位置点上灰度级值的大小，即只反映了黑白灰度的关系。
数字化采样一般是按正方形点阵取样的， -each of the matrix elements known as a pixel, pixels or image elements. And g (i, j), speaking on behalf of (i, j) of the gray values, brightness value. As g (i, j) on behalf of the image point of light intensity (brightness), but just a form of energy, the g (i, j) must be greater than zero, and has limited value, namely : 0 "= g (i, j)" 2n. By g (i, j) to indicate the numerical (i, j) position on the point value of the gray-class size, that is, only reflects the intensity of black and white relations.

Description: 图像集群（Image Clustering）
(1)图像读入，显示图像所在路径；
(2)采用imgcluster函数进行图像集群，选择集群个数后进行图像集群；
(3)运行后，在原图像上显示集群灰度图；
(4)若要显示各个集群情况，可打开【Show Clustering Image】新窗体，显示各集群类的基于原图的彩绘区域。其中非当前集群范围，则显示灰度为255的黑色。用户可点击按纽上下查看所有集群图。-image cluster (Image Clustering) (1) read into the images, Images show host path; (2) use of imgcluster function for image clusters, After the number of clusters chosen for image clusters; (3) After the operation, in the original image displayed on the gray level clusters; (4) To show that the various clusters, [Show Open Clustering Image -- new windows, showed that the cluster type based on the maximum of regional painting. Clusters of non-current range, it shows that the intensity of 255 black. Users can click on View All button next cluster map.

Description: 算差分盒维数的matlab程序。 让窗口中的每个像素都对分数维作出贡献。首先,计算某一尺度窗口的平均灰度值 ,然后判断每一个像素的灰度 ,若大于灰度平均值 ,则累加其灰度值为 max ,若小于灰度平均值 ,则累加其灰度值为min ,用max 和min代替 在 Sarkar 和 Chaudhuri 算法中的最大值和最小值 ,再通过拟合求出分数维。 -Differential count box dimension matlab program. Let window on the fractal dimension of each pixel to contribute. First, the calculation of an average gray scale of the window, and then determine the gray scale of each pixel, if the intensity is greater than the average, the cumulative value of its gray max, if less than the average gray level, the accumulation of its gray value of min, max and min to use instead of the algorithm in Sarkar and Chaudhuri maximum and minimum, and then by fitting the calculated fractal dimension.
