counters = zeros(1,10);
Hpart = YourImageAsHSV(:,:,1);
for K = 1 : numel(Hpart)
if Hpart(K) < 255/10
counters(1) = counters(1) + 1;
elseif Hpart(K) < 2*255/10
counters(2) = counters(2) + 1;
elseif Hpart(K) < 3*255/10
counters(3) = counters(3) + 1;
elseif Hpart(K) < 4*255/10
....
else
counters(10) = counters(10) + 1;
end
end
counters is now the 10-bin histogram of the "H" part of the HSV image.
