WebRobustness to variations in lighting conditions is a key objective for any deep vision system. To this end, our paper extends the receptive field of convolutional neural networks with two residual components, ubiquitous in the visual processing system of vertebrates: On-center and off-center pathways, with an excitatory center and inhibitory surround; OOCS for … Web1 For on center off surround receptive fields, light hitting the entire receptive field will inhibit glutamate release from all three photoreceptors. This means that the bipolar cell will be activated as a result of the center photoreceptor (reduced glutamate) but since the horizontal cells will not be active (reduced glutamate) they won’t help
