The ratio of the minimal box area to the object area is different for different shapes: compare the back and grey areas in (a) for a crystal-like object and in (b) for an object typical of skin on the drop. The ratio of the area to perimeter of an object is also different for different shapes: compare the length of the black boundaries with the grey areas in (c) for the crystal-like object and in (d) for an object similar to those obtained for precipitate. |
