When a human being interprets two-dimensional images as three-dimensional objects, he usually also reconstructs the shape of the hidden part. It is common for the shape of the visible part to remind him of the hidden part. The human visual system must incorporate the ability to reconstruct the shape of a hidden part from the monocular image. Introduction of the orthogonality of the directions of the edges may be a reasonable strategy to restore the two-dimensional view to its original state, since artificial structures emphasize the aspect of right angles. A local energy function is defined to evaluate the orthogonality of two edges. This function represents the deviation from the right angle. Minimizing the summation of the local energy enables us to recover the shape of the visible part. Three concepts of geometrical restriction, continuity of planes, and minimization of local energy can produce the optimum alternative which describes the hidden part. Several experiments yield results of similar interpretation as by a human being, and demonstrates that the present method may be applicable to animation recognition.
