how to combine multiple local binary pattern operators i.e. LBP(1,8) and LBP(3,16)???

i am implementing multi scale analysis for local binary pattern for feature extraction.

i want to know how to combine multiple LBP operators with different radius and neighbor pixels applied on same image.

e.g.: LBP code with r=1, nghbr=8 and

LBP code with r=3, nghbr=16.
