Current mode elementary motion perception neural cell

The paper proposes biologically inspired NN architecture that employs neural correlation of motion detection via a two-channel mechanism similar to the visual system of invertebrates that is capable of detecting the direction of motion. The correlation-based scheme with mutual lateral inhibition is adopted to implement current mode VLSI neuromorphic cells with the dynamics characterized by a first order nonlinear differential equation. Such cells act as elementary motion detectors (EMDs) sensitive to the direction of motion and can be implemented as a front-end section of a sophisticated object tracking system. Spatio-temporal responses of the VLSI model are investigated and simulation results are given.
