Abstract:
A set of images is acquired of a scene while illuminating the scene with a set of colors with different hues. The set of colors is generated by a set of light sources arranged in a substantial circular manner around a lens of a camera to form a hue circle, wherein each light source emits a different color. A shadow confidence map is generated from the set of images by using hues and saturations of pixels in the set of images. Then, depth edges are extracted from the shadow confidence map.
