%GFNORMRESPF2 2-D filter response using frequency domain filters (REPLACED).%%   GFNORMRESPF2 IS REPLACED BY GFRESPF2 AND WILL BE REMOVED IN FUTURE%   VERSIONS, USE GFRESPF2 INSTEAD.%%   [R] = GFNORMRESPF2(N1, N2, GF,S) calculates the normalized%   response R of Gabor filter GF for the 2-D signal S. GF should%   be given in frequency space (use GFCREATEFILTERF2) and S in%   spatial space (gray level image, etc.)%%   Examples%%   See also GFCREATEFILTER2, GFRESPF2.%% References:%   [1] Kamarainen, J.-K., Kyrki, V., Kalviainen, H., Gabor%       Features for Invariant Object Recognition, Research%       report 79, Department of Information Technology,%       Lappeenranta University of Technology %% Author(s):%    Joni Kamarainen <Joni.Kamarainen@lut.fi>%    Ville Kyrki <Ville.Kyrki@lut.fi>%% Copyright:%%   The Gabor Features in Signal and Image Processing Toolbox is%   Copyright (C) 2000 by Joni Kamarainen and Ville Kyrki.%function [r]=gfnormrespf2(gf_, s_);% spatial centered signal -> uncentered frequency spectra ffts = fft2(ifftshift(s_));% response matrixr = fftshift(ifft2(ffts.*gf_));
