	abstract =	{Gabor filters have been widely used for modeling cortical
	cell frequency and orientation selectivity properties, as well as for
	image processing routines including segmentation and shape-from-texture
	[1], [2], [3]. Because there are many frequency and orientation
	selective channels in the early visual cortex, the computation of
	multiple Gabor filter outputs are necessary for the computational
	modeling of the human visual cortex.  However, obtaining the outputs of
	these frequency and space localized Gabor filters is computationally
	very expensive. A local Fourier transform based technique is proposed
	to compute the outputs of multiple Gabor filters.  Significant speedup,
	approaching one order of magnitude is obtained over the standard FFT
	based convolution for the computation of multiple Gabor filter outputs.
	This algorithm saved many hours of processing time in the simulations
	of the human cortical processing we have been performing on the
	massively parallel computer, the MasPar MP-1104.},
