Differentiators for Insect Vision Motion Detection

摘要

In this paper we review two motion dection models based on insect's visual system. The two motion detection models are the Hbrridge template model and the Reichardt correlator model, both have been implemented in analog VLSI. We briefly review the VLSI implementation of "the two motion detection models and identify the difficulties in designing the required large RC time constants in VLSI. Possible circuit designs to obtain RC time constants in the order of 10-100 ms are presented.
