Local binary patterns

Minor updates added

Resolved a few bugs related to circishift (found by Michael and Olga) and sort. Added if changing function behavior based on Matlab version.

Removed duplicated outdated files. thanks to Olga for finding this.

Resolved the bug reported by Michael.

The function “roundnS” was added to the submission aimed to replace the “roundn” function that is apparently part of the Matlab Mapping Toolbox, which may be missing from some of the users trying to run this code.

Changed filter direction (to CCW), starting point (3 o'clock instead of 12), support pixels interpolation.

- Support Circular filter, as in M. Pietikäinen papers.
- Works on multiple color channels (gray-scale, RGB, La*b and even spectral images).
- Support Rotation Invariant mode.
- Two LBP version- pixels wise, and efficient.
Enjoy

A Helix/Snail indexing function was аdded to scan neighborhood pixels as spiral.

Many thanks goes to Chris Forne for his sharp eye. Bugs fixed, and some modification introduced.
