For eg (below is pseudo-code in Python-OpenCV) # define ROI of RGB image 'img' roi = img[r1:r2, c1:c2] # convert it into HSV hsv = cv2. On Gimp (or other photo manipulation sw) Hue range from 0 to 360, since opencv put color info in a single byte, the maximum number value in a single byte is 255 therefore openCV Hue values are equivalent to Hue values from gimp divided by 2.
