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)); See also FBAPPLY2D Piotr's Image&Video Toolbox Version 2.0 Copyright 2008 Piotr Dollar.
