Provided by Johann Schoonees [j.schoonees@irl.cri.nz]. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% To run the adaptive filtering demosaicking algorithm, out = AFdemosaick(in,lp_flt) in input image with full RGB values lp_flt low pass filter for green CFA pixels out output demosaicked image Default low pass filter lp_flt = [ 0 1 -2 1 0; ... 1 -4 6 -4 1; ... -2 6 56 6 -2; ... 1 -4 6 -4 1; ... 0 1 -2 1 0]/*** is our designed filter for extracting luminance component at green pixels. You can try your own designed filter by input lp_flt. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Please email us for questions and comments.
