Consumers of digital photography have come to have high expectations of the rapidly expanding market, including artifact-free photographs and the ability to easily edit their digital pictures. Today’s high-resolution cameras allow the smallest relative motions to be detected. The analysis of these motion-based depth cues is useful for processing enhanced photographs of the 3D world. The Inventors have developed an efficient technique to store information regarding the relative motion objects in a scene for superior in- and off-camera processing and image editing. This technique specifically applies to occluding contour detection, which enhances edge perception in still images for enhanced 3D image processing.
