Abstract

An APS (Active Pixel Sensor) with 2D winner-take-all detection is presented. The system employs adaptive spatial filtering of the processed image with bad pixel elimination and false alarm reduction in case of a missing object. The circuit has a unique ability of adaptive spatial filtering that allows removal of the background from the image, one stage before it is transferred to the WTA detection circuit. A test chip of 64*64 has been implemented in 0.5 μm CMOS technology, 3.3V supply and is expected to dissipate 128mW at video rate. System operation is discussed and simulation results are presented.
