Crop the image, so thjat there is no white along the backgrounds.

I = imread('untitled.png') ;
I1 = rgb2gray(I) ;
[y,x] = find(I) ;

N = 4 ;   % number of N's in the image 
idx = kmeans([x y],N) ;

imshow(I)
hold on
data= cell(N,1) ;
for i = 1:N
    data{i} = [x(idx==i),y(idx==i)] ;
    plot(data{i}(:,1),data{i}(:,2),'.','color',rand(1,3))
end

The output of the above code is attached. I want the program to take the input image ( in this case the image with the ns but it doesn't necessarily have to be limited to letters) and then display 5 different images each having one of the different ns

You can very much plot each N. You have that in data.
