USAGE

1. Compile the mex_computeLBPonKeypoints.cpp file if necessary (the pre-
   compiled versions for 64-bit Linux and 32/64-bit Windows are provided,
   and usually they will work):
   
   >> mex mex_computeLBPonKeypoints.cpp


2. Run extract_OCLBP_descriptor.m to compute gray/color OC-LBP descriptor
   (see the M-file for more detailed instruction of each input arguments):
   
   >> load 000019_kps.mat
   >> descs = extract_OCLBP_descriptor('000019.jpg',kps,8,1,'gray')

ACKNOWLEDGMENT

Great thanks to Machine Vision Group, University of Oulu for sharing their
code of LBP, which is used in the OC-LBP function.
