I am working on improving a "Face recognition" project in which there is a matlab code which uses "LTP ( Local Terinary Pattern )" and "DOG (difference of Gausiann Filter)". I am trying convert this Matlab part to Opencv.
Is there any good implementations of "LTP" and "DOG" in opencv? The current "LTP" is the implementation of this paper - Enhanced Local Texture Feature Sets for Face Recognition Under Difficult Lighting Conditions by Xiaoyang Tan and Bill Triggs.
I found a code for "LTP" here in opencv. But it just looks like pre-processing step? Can some one refer to some LTP C++/Opencv implementations?
