Figure 1. An artificial vision system based on reconfigurable ion-modulated memtransistors inspired by the human visual recognition system. a) Schematic diagram of the conventional image recognition systems, including image denoising and classification algorithm running on the processors. b) Schematic illustration of the human visual system, the optic nerve fibers transmit impulses to the visual cortex when receiving stimulus at the retina from images of the outside world. c) Proposed neuromorphic artificial vision systems based on the reconfigurable ion-modulated memtransistors, which can act as filtering units, in-memory inference weights and activation neurons simultaneously.
