Since all texture analysis methods in this table are variants of LBP, N in the table represents the length of a LBP histogram generated with log₂ N-pixel neighborhood. Ind-LBP is short for the method that applies LBP to each color channel separately, and it is listed in this table as an typical example in the category of independent color texture analysis paradigm.
