In this paper, a new codification of Local Binary Patterns (LBP) is given using graph pyramids. The LBP code characterizes the topological category (local max, min, slope, saddle) of the gray level landscape around the center region. Given a 2D grayscale image I, our goal is to obtain a simplified image which can be seen as "minimal" representation in terms of topological characterization of I. For this, a method is developed based on merging regions and minimum contrast algorithm.
