提出了一种用于稠密正常流估算的92/SPL次/52有源像元传感器(APS)。该传感器在同一芯片上高效地将成像和处理结合在一起。该算法计算关于时间和空间的偏导数，并使用它们的比率来计算法向流速。该芯片采用CMOS0.5/Splu/m工艺制造，面积为4.5 mm/sup 2/，在V/subdd/=5V时功耗为2.6 mW。
A 92/spl times/52 active pixel sensor (APS) for dense normal flow estimation is presented. The sensor combines imaging and processing on the same chip efficiently. The algorithm computes partial derivatives with respect to time and space and uses their ratio to compute normal flow velocity. The chip, which has been fabricated in a CMOS 0.5 /spl mu/m process, occupies an area of 4.5 mm/sup 2/ and consumes 2.6 mW power at V/sub dd/=5 V.
