I have read the Wikipedia doc where interpolation for 4 pixels discussed very nicely in this link https://en.wikipedia.org/wiki/Bilinear_interpolation inside the heading nonLinear. I required for 9 pixels or say 3by3 window? could some body explain me like wikipidia for 9 pixels, how can apply

Where are you getting your definition from for 9 pixels? For 4 pixels the logic is obvious as they are the 4 that surround the point of interest, but how are you defining the 9 pixels?

Actually, I was looking for LBP I am attaching paper over here, for P=8, and R=3.0, Paper Multiresolution Gray-Scale and Rotation invariant texture classification ith local binary pattern
