contrast coding

contrast coding Contrast coding is a way the visual system represents a scene by emphasizing differences between a location and its surrounding area rather than their absolute brightness.

Contrast coding is a way the visual system represents a scene by emphasizing differences between a location and its surrounding area rather than their absolute brightness. In the retina, center-surround receptive fields created by lateral inhibition support this efficient coding of spatial contrast.
