On the Control of Attentional Processes in Vision

An Empirical Method to Quantify the Peripheral Performance Degradation in Deep Networks
When applying a convolutional kernel to an image, if the output is to remain the same size as the input then some form of padding is required around the image boundary, meaning that for each layer of convolution in a convolutional neural network (CNN), a strip of pixels equal to the half-width of the kernel size is produced with a non-veridical representation.
