Summary:
This heuristics computes a Local Binary Pattern (LBP)
Description:

It compares the pixel values to the center pixel.


x x x
x o x
x x x


The pixels x are compared to the value of the pixel o. Result returned is an LBP code value (8 bits example : 00100111). If x is greater than o the returned value is 1 otherwise 0.


In the following example:


110 160 205
111 150 130
90 155 85


the pixels are compared to the center pixel value 150 so the LBP code will be [01100010]
