Abstract
A multi-resolution background adaptation system and method wherein image information for a video frame is analyzed to update a background image in as great a resolution as possible. The video frame is partitioned into a plurality of cell levels, each cell level comprising at least one cell. Each cell is further partitioned into children cells for several hierarchical levels. Background image adaptation begins at the frame level and proceeds to lower cell levels of smaller cells when the lower cell levels are not substantially occluded by objects.
