try this :
% Convert the image from rgb into hsv color space: hsvImage = rgb2hsv(rgbImage); % Extract the hue image h = hsvImage(:,:,1); % Get the histogram counts = histcounts(h, 1000); % Find peaks in the histogram [peaks, indexes] = findpeaks(counts); % count the number of peaks numberOfHues = length(peaks)
