Webb1 Answer. You can simply specify a ROI for that region and convert it into HSV. # define ROI of RGB image 'img' roi = img [r1:r2, c1:c2] # convert it into HSV hsv = cv2.cvtColor (roi,cv2.COLOR_BGR2HSV) Now it gives you the hsv values of the region. Your object may comprise some part of the ROI. WebbMoving on from the “frequency table” above, a true histogram first “bins” the range of values and then counts the number of values that fall into each bin. This is what NumPy’s histogram() function does, and it is the basis for other functions you’ll see here later in Python libraries such as Matplotlib and pandas.
