Convolution
Pascal Wallisch
The purpose of this chapter is to familiarize you with the convolution operation. You will use this operation in the context of receptive fields in the early visual system as input response filters whose convolution with an input image approximates certain aspects of your perception. Specifically, you will reproduce the Mach band illusion and explore the Gabor filter as a model for the receptive field of a simple cell in the primary visual cortex.
