2 dni temu · This can be done as follows: cx = int (M [ 'm10' ]/M [ 'm00' ]) cy = int (M [ 'm01' ]/M [ 'm00' ]) 2. Contour Area. Contour area is given by the function cv.contourArea () or from moments, M ['m00']. area = cv.contourArea (cnt) 3. Contour Perimeter. It is also called arc length. It can be found out using cv.arcLength () function.
