Abstract
A method enhances an output image of a 3D object. A set of input images are acquired of a 3D object. Each one of the input images is illuminated by a different one of a set of lights placed at different positions with respect to the 3D object. Boundaries of shadows are detected in the set of input images by comparing the set of input images. The boundaries of shadows that are closer to a direction of the set of lights are marked as depth edge pixels.
