The application target is real-time foreground/background video segmentation. The approach to video segmentation is based on depth information obtained from a stereo camera. The lower-level image processing needed to construct the associated depth maps is supported by DRL-based modular pipelined datapaths, assembled to match the image characteristics and the needs of the higher-level segmentation algorithms. Several working demonstration systems validate the overall approach, the algorithms and the implementation choices.
