Abstract :
It was recently proposed that a neural shifter circuit could be responsible for compensating for image motion so as to produce an unblurred image in visual cortex. An analysis of the motion blur problem in the frequency domain is presented, and it is shown how a neural shifter circuit behaves as a filter within this domain in order to extract spatial information from moving images. From this analysis it is possible to formally compare the shifter circuit to other computational strategies for reducing motion blur, such as spatio-temporal filters. A control systems analysis of the shifter circuit that allows one to predict how neural time delays affect the performance of the system is provided. The results of a computer simulation of a shifter circuit are presented
