Hey I have this binary image, with the centroids detetced but I need a way to count them so I get an output as number of characters is 7. I haven't been able to find a function or any way to do this. CountImage.jpg

Only using 2 centoids? (1 and 2)?
plot(centroids(:,1),centroids(:,2),'b*')

Why not simply label the binary image? and 'Num' would be the number of characters.
[Label, Num]=bwlabel(Image)
