how to implement LTP Feature extract

Hi everyone,

i have see code in matlab " extractLBPFeatures" , code as bellow, if LTP how to change (LTP is are an extension ), pls help me and explain how to thanks everybody

{

% -----------------------------------------------------------------

function lbp = computeMultibyteLBP(I, x, y, numNeighbors, interpolation, numBytes, offsets, weights)

coder.inline('always');

lbp = zeros(1,numBytes,'uint8');

center = I(y,x);

p2 = coder.internal.indexInt(numNeighbors);

p1 = coder.internal.indexInt((8*numBytes)-7+1);

for n = coder.unroll(1:numBytes) % MSB [xxxx] LSB

for p = p2:-1:p1 % reverse order b/c of bitshift to left

if strcmpi(interpolation, 'linear')

neighbor = vision.internal.LBPImpl.bilinearInterp(I, x, y, p, offsets, weights);

else

neighbor = vision.internal.LBPImpl.nearestInterp(I, x, y, p, offsets);

end

lbp(n) = bitor(lbp(n), uint8(neighbor >= center));

lbp(n) = bitshift(uint8(lbp(n)),uint8(1));

end

% bit p1-1

if strcmpi(interpolation, 'linear')

neighbor = vision.internal.LBPImpl.bilinearInterp(I, x, y, p1-1, offsets, weights);

else

neighbor = vision.internal.LBPImpl.nearestInterp(I, x, y, p1-1, offsets);

end

lbp(n) = bitor(lbp(n), uint8(neighbor >= center));

% next byte

p2 = p1-2;

p1 = p2-7+1;

end

end
