The LLBP tests the relation between pixel and its neighbors, encoding this relation into a binary word. This allows detection of patterns/features. The current version uses horizontal and vertical shaped filter, resulting in "line" shape, for which the name is given.
An illustration of Line LBP can be seen here: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3251987/figure/f6-sensors-11-11357/
While this shape implies options for specific efficient 1D filter based implementation, here I implemented it via wrapping of my "efficientLBP" function- which achieves not optimal, but reasonable run-time. And I like code reuse :)
