title: How to implement LBP uniform
body: <p>I'm new in OpenCV. I'm trying to do a sample to extract the features of a face. I'm rading several papers and one of the most recommended was LBP. I understand how to works LBP descriptor but I read a variant from it. LBP uniform I understand it is as LBP original but once you have binary sequence (e.g you compare a particular pixel with the neighboors and you have next result -> 11110001, I understand there are 2 transitions, so in that case we can say it is uniform because number of transitions is &lt;= 2. </p>
  
  <p>My question is what code I have to comput in that pixel after doing this process. I know with the  LBP original wew have 256 values but with this variant from LBP uniform que reduce the number to 59 bins values. So my question is what code I have to put after testing if the number of transitions in every pixel is &lt;=2 or >2.</p>
  
  <p>Thanks! I hope I had explained correctly.</p>
