SYSTEM AND METHOD OF FOREGROUND EXTRACTION FOR DIGITAL CAMERAS |
摘要 |
A system and method of foreground objection extraction in connection with detection of single color objects in video frames. A laser emitter in combination with a random, textual pattern producing element illuminates a field of view thereby producing a background frame. The pattern is projected onto single color objects in the field of view. A current frame is compared to one of the background frame, or a prior frame to determine if there are any differences. Responsive to any detected differences, foreground objects are extracted from the current frame, without shadows, light spots or reflections. |
