Abstract—This paper describes the early vision of bio-inspired neuromorphic system, mimicking the primitive behaviour of visual cortex. The proposed bio-inspired vision exhibits the biologically plausible function of mimicking the cat’s visual cortex experimentation of Hubel and Wiesel. The neuromorphic implementation of vision is inspired by the directional visual signal selectivity of cortex and the CMOS spiking neuron based on Hodgkin-Huxley formalism. The feasibility of neuromorphic early vision is demonstrated for applications of the transportation safety system of passengers’ occupancy detection of 95%, based on the recognition of human head figures.
