Hello,
I want to show cluster save in cell.
binary image i show cluster
Z = cellfun(@(Z) Z', Z,'Un',0);
Z = cellfun(@(Z) cell2mat(Z), Z,'Un',0);
Z = cellfun(@(Z) sub2ind(size(I) , Z(:,1) , Z(:,2)), Z,'Un',0);
figure
cluster = zeros(size(I));
for ii = 1:length(Z)
cluster(Z{ii}) = ii;
end
imshow((cluster))
when I have a grayscale image, how i show cluster in image ?
Thanks

Try putting "hold on" and plotting the clusters
plot(x, y, 'r*', 'MarkerSize', 15);
which puts an asterisk at the location of every data point in the data set. If they're clustered, you'll see clusters of asterisks.
