The present invention provides a system and method for simultaneous variational and adaptive segmentation of single non-overlapping and multiple overlappingoccluded-objects in an image scene. The memory includes a memory array having a plurality of memory cells coupled to bit lines. Exemplary kinds of storage format information include compression mode, a packing mode for storing Z data in tiles or color data in tiles, and a mode for allocating tile data among partitions in a partitioned memory. The bearing retainers are made of an elastic electrically insulating body.
