In this abstract we extend ideas and results submit-
ted to [3] in which a new codification of Local Binary Patterns
(LBP) is given using combinatorial maps and a method for
obtaining a representative LBP image is developed based on
merging regions and Minimum Contrast Algorithm. The LBP
code characterizes the topological category (max, min, slope,
saddle) of the 2D gray level landscape around the center region.
We extend the result studying how to merge non-singular slopes
with one of its neighbors and how to extend the results to non-
well formed images/maps. Some ideas related to robust LBP and
isolines are also given in last section.
