     @param radius The radius used for building the Circular Local Binary Pattern. The greater the

     @param neighbors The number of sample points to build a Circular Local Binary Pattern from. An
     appropriate value is to use `8` sample points. Keep in mind: the more sample points you include,
     the higher the computational cost.
