Method

Lets you choose a method to determine the pattern:

default… Original local binary pattern which is grayscale invariant but not rotation invariant.

ror… Extension of default pattern which is grayscale invariant and rotation invariant.

uniform… Uniform pattern which is grayscale invariant and rotation invariant and offers finer quantization of the angular space.

var… Variance of local image texture (related to contrast) which is rotation invariant but not grayscale invariant.
