Motion estimation is a major computational task in real-time vision circuits and artificial retinas that require energy- efficient, high-speed, and microminiaturized circuitry. Traditionally, the motion estimation is made by means of velocity-tuned filters (VTFs), a class of spatiotemporal signal processing circuitry. However, conventional VTFs have limitations in area, power, and speed for real-time motion computation because they employ bulky and slow analog circuitry. In this paper, we… CONTINUE READING
