Method, system and apparatus for updating a scene model

摘要

- 41 Abstract METHOD, SYSTEM AND APPARATUS FOR UPDATING A SCENE MODEL A method of updating a scene model for a foreground segmentation of an input image 5 captured from a camera, is disclosed. One or more visual elements of the input image are determined. A spatial relationship between at least one of the visual elements and the scene model for a foreground segmentation of the input image is determined. The method updates the scene model for determining the foreground segmentation of the input image based on the determined spatial relationship. 8169809vl (P095093_SpeciAs Filed) Start - --- -305 Create- seed points/ tDetermi ne boundary strength iage 320 Add a fixed offset 330 Add Random noise: offset Perturb locations of se ed: points away from strong image boundaries --------- -----------3 5 0 : Determine geodesic 370 distance transform Reinitialise seed p oints: to: superpixel centroids 350 Yes. - s- N/ Further "N~refiement?.I' No Fig. 3 End
