Compactness coefficient (CmpC) is defined as the ratio of the watershed perimeter to the circumference of equivalent circular area.
Elongation ratio (ElnR) is defined as the ratio of diameter of a circle of the same area as the watershed to the maximum watershed length. The numerical value varies from 0 (in highly elongated shape) to 1 (in circular shape).
Circulatory ratio (CrcR) is defined as the ratio of watershed area to the area of the circle having the same perimeter as the watershed perimeter. The numeric value may vary in between 0 (in line) and 1 (in a circle).
