Crop a 2D filterbank (adjusting filter norms).
Takes a filter bank and crops it by cropping off delta pixels from each
side. Ensures that the mean response of each filter is 0 and that the L1
norm is 1, i.e. sum(sum(abs(F)))==1.
USAGE
FBC = FbCrop( FB, delta )
INPUTS
FB - original filterbank
delta - amount to crop by
OUTPUTS
FBC - cropped filterbank
EXAMPLE
load FbDoG.mat; FBC=FbCrop(FB,4);
figure(1); montage2(FB,struct('extraInfo',1));
figure(2); montage2(FBC,struct('extraInfo',1));
