Mach bands and multiscale models of spatial vision: the role of first, second, and third derivative operators in encoding bars and edges.

abstract：:Sensory neurons represent stimulus information with sequences of action potentials that differ across repeated measurements. This variability limits the information that can be extracted from momentary observations of a neuron's response. It is often assumed that integrating responses over time mitigates this limitati...
