Signal Sharpening

Signal Sharpening is a computational mechanism within the broader class of perceptual processing strategies that enhances the precision of neural signals by differentially amplifying dominant inputs while suppressing weaker, adjacent ones, thereby increasing contrast and spatial resolution in sensory representation.
