Erratum to: Adaptive Matrices and Filters for Color Texture Classification

And lines 187–198 should read as: As pointed out in [35]: “another extension to the original operator is the definition of the so called uniform patterns, which can be used to reduce the length of the feature vector and implement a simple rotation-invariant descriptor. This extension was inspired by the fact that some binary patterns occur more commonly in texture images than others. A local binary pattern is called uniform if it contains at most two transitions from 0 to 1 or vice versa when it is traversed circularly. Ojala et al. [24] noticed in their experiments that uniform patterns account for a little less than 90 % of all patterns when using a (8, 1) neighborhood and for around 70 % with a (16, 2) neighborhood.”
