This paper describes the early vision of bio-inspired neuromorphic system, modelling the primitive behaviour of visual cortex to implement the robust performance of detecting vehicle passengers for the new emergency system for vehicle accident (ePOST). The proposed neuromorphic vision mimics the cat’s visual cortex experimentation of Hubel and Wiesel. The directional visual signal selectivity of cortex is introduced to implement the neuromorphic vision 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 based on the recognition of human head figures.

This paper describes the bio-inspired neuromorphic vision system, which can mimic the primitive function of visual cortex. The robust performance of proposed neuromorphic system is evaluated by monitoring vehicle passenger’s safety status, such as occupancy, fastened seatbelt, activated airbag, which is based on the simulated simple cell function of visual cortex experimentation by Hubel and Wiesel as well as the neuromorphic circuit with CMOS transconductance. The neuromorphic vision system demonstrated successfully the detection of passenger occupancy and the status of safety seat belt from the images from the widely changing environment of vehicle on the road. The detection of inflated airbag is tested with success for the video taken from the collision test, illustrating the feasibility of this idea to further extended applications utilizing the electronic implementation using CMOS technology.
