1. A method of parsing a human body image, the method comprising: acquiring a depth image including a human body; and detecting a plurality of points in the acquired depth image by conducting a minimum energy skeleton scan on the depth image, wherein the minimum energy skeleton scan corresponds to detection of the plurality of points in the depth image by minimizing an energy function for the depth image, the plurality of points corresponding to a skeleton point, and the energy function corresponds to a logarithm of a sum of opposite numbers for a probability that a pixel of the depth image is predicted as a skeleton point or a non-skeleton point.
