Abstract METHOD, APPARATUS AND SYSTEM FOR DETERMINING A BOUNDARY OF AN OBSTACLE WHICH OCCLUDES AN OBJECT IN AN IMAGE A method of determining a boundary of an obstacle which occludes an object in an image, is disclosed. At least one object in the image and a further image captured by a camera (e.g., 101) is determined. A plurality of regions in which the at least one object is detected, is determined from the images. Locations of edges of the plurality of regions are determined A 0 common location is determined from the determined edges. The boundary of the obstacle is determined, where the boundary comprises a part of the edges at the common location. 6821201v1(P050145_As Filed -6/11 Strt , : Sta ,t500 Determine boundary pixel 520 530 location and orientation for each motion envelope Determine static 525 occlusion Unprocessed motion n likelihood from envelope? accumulated boundary yes persistence Detect overlapping motion 535 envelopes for targets subject to same occlusion , ,End Discard silhouette boundary 540 pixels inside overlapping motion envelopes Determine boundary persistence at 545 each remaining boundary pixel of the motion envelope Accumulate boundary persistence 550 Fig. 5 for each quantized image location and orientation 6821113vl (P050145_DrawingsAs Filed) |
