File Information

While Matlab scans/indexes matrices column-wise, some algorithms demand Snail/Escargot/Helix indexing (LBP is the last case I've encountered this issue). This functions implements (very shortly and intuitively if I may add) such an indexing, missing from Matlab indexing methods.


This file inspired Opposite Color Local Binary Patterns (Oc Lbp).
