如何申请Matlab的模糊C均值（FCM）输出用于图像分割

Question

我有我使用fcm.m试图区段的2D灰度图像（=数据）：

Nc=2; %number of clusters is 2 

[centers,U] = fcm(data,Nc); 

如何申请fcm.m的输出来分割原始图像。我找不到在线的工作示例。

Answer 1

只是做reshape：

img = im2double(imread('cameraman.tif')); 
Nc = 2; %number of clusters is 2 

[centers,U] = fcm(img(:),Nc); 
subplot(121); 
imshow(reshape(U(1,:),size(img)),[]) 
title('fuzzy membership for class 1') 
colorbar() 
subplot(122); 
[~,I] = max(U,[],1); 
imshow(reshape(I,size(img)),[]) 
title('hard membership') 
colorbar()
