附件是matlab附带的图像，cameraman.tif但在应用[fuzzy c-means] 1之后
此外，算法的输出是u2（像素的隶属度）。有关此数据，请参见matlab.mat。
我想要做的是从附加的图像中选择像素，其u2值为equal to 1.
关于如何做到这一点的任何想法matlab？
谢谢。

获取适当像素的索引：
ind = find( u2 == 1 ); % return indices of all pixels with u2 eq to 1
自己获取像素
pixels = img( ind );

Alternatively, you can avoid using find and go straight into logical indexing.
Given an image as:
>> image = [1 3 5; 2 3 1; 3 2 2]
image =
1 3 5
2 3 1
3 2 2
you can find the pixels with value 2 using the condition iamge == 2:
K>> image == 2
ans =
0 0 0
1 0 0
0 1 1
If for instance you want to manipulate these pixels by setting them to 7 you can easily do that with a single line:
image(image == 2) = 7
image =
1 3 5
7 3 1
3 7 7
