How to visualize communities in image by the vector of communities

Hello,

my problem is how i can showing the communities in image by the vector of commuities, for exemple i have my image:

I=imread('myimage');

after i obtain the adjacency matrix of this image:

A= Adjacency_matrix(I);

and now i apply my algorithme to detect the communities:

com=myalgorithm(A);

where com is the vector of communities, so how i can showing the communities in the image by this vector.

Thank you in advance.

I don't know what you mean by communities. Do you mean clusters? Please show your image and adjacency matrix. Explain what adjacency matrix means. Is that the gray level cooccurrence matrix?
