excellent work.

I meet one problem.
When I use chlbp.c, here is the samples in chlbp.c

clear, close all
load viola_24x24
Ny = 24;
Nx = 24;
options.N = [8 , 4 , 12];
options.R = [1 , 1 , 2];
options.map = zeros(2^max(options.N) , length(options.N));

mapping = getmapping(options.N(1),'u2');
options.map(1:2^options.N(1) , 1) = mapping.table';
options.map(1:2^options.N(2) , 2) = (0:2^options.N(2)-1)';
mapping = getmapping(options.N(3),'u2');
options.map(1:2^options.N(3) , 3) = mapping.table';
options.shiftbox = cat(3 , [Ny , Nx ; 1 , 1] , [16 , 16 ; 4 , 4] , [Ny , Nx ; 1 , 1]);

options.T = 50;

H = chlbp(X , options);

after this I type

 H2 = chlbp(X(:,:,2) , options);

and i find H2 is different H(:,:,2)?why?
