Four representative examples demonstrating how the centers in original images are detected to be present or inferred, showing the original image (left) and the corresponding parameter values (right) of each example; (a) the case in which two hands are present so the center is inferred; (b) the case in which only one hand is present so the center is inferred; (c) the case in which no hands are present but a data point exists near to the center of the contour; and (d) the case in which no center point is present or inferred. * Total score/score of contour/score of numbers/score of hands/score of center.
