Description: OTSU Gray-level image segmentation using Otsu s method.
Iseg = OTSU(I,n) computes a segmented image (Iseg) containing n classes
by means of Otsu s n-thresholding method (Otsu N, A Threshold Selection
Method from Gray-Level Histograms, IEEE Trans. Syst. Man Cybern.
9:62-66 1979). Thresholds are computed to maximize a separability
criterion of the resultant classes in gray levels.
OTSU(I) is equivalent to OTSU(I,2). By default, n=2 and the
corresponding Iseg is therefore a binary image. The pixel values for
Iseg are [0 1] if n=2, [0 0.5 1] if n=3, [0 0.333 0.666 1] if n=4, ...
[Iseg,sep] = OTSU(I,n) returns the value (sep) of the separability
criterion within the range [0 1]. Zero is obtained only with images
having less than n gray level, whereas one (optimal value) is obtained
only with n-valued images.- OTSU Gray-level image segmentation using Otsu s method.

image. The user inputs at least two inputs: IMGIN and NCLUSTERS, and this
function will step through an interactive color segmentation using kmeans clustering. It is interactive in that the user will be prompted to click-define the target colors in the segmentation.-This function implements kmeans clustering on an input RGB (m x n x 3)

Description: 出了一种新的图像分割方法。这种分割方法首先利用粗糙集理论将图像按照一定的规则划分为
大小相等的若干图像子块，而后利用蒙特卡罗方法基本原理对划分的图像子块进行一定规模的随机抽样，以随机抽
样所得的图像子块为样本进行粗糙熵计算，用所得最大粗糙熵所对应的灰度值为分割阀值对图像进行分割，在采用
较小的图像子块划分以取得更好的分割效果的情况下，极大的提高了算法的分割速度。通过对测试图像的
MATLAB仿真试验验证了算法在降低计算机消耗方面的有效性，且所得的分割阀值也令人满意。-The image segmentation algorithm was presented．First of all，it divides the image into some equal SI‘Ze image sub

Methods，and computes the rough entropy of the sample，and then divides the image by the image gray scale corresponding to the maximum rough entropy．The speed of the image segmentation is largely improved，while adopting the less image sub—
pieces to get better segmentation effect．And it has been confirmed in reducing the consumption of the computer is very effective in experiments using MATLAB，and the threshold is satisfied． Platform: |
