Hello all,
   
  Can any body let me know how exactly Iterativeclosestpoint2 works with out knowing the correspondence points? I Understood that the iteration starts by the predefined initiated transform,and it will continue until it reaches the convergence criterion!!!but how?
  I mean how the optimizer works without knowing the correspondence points?How the error is calculated?
  I have some problem with the concept of this point set registration!!!!!!!!!!!
  Any help is appreciated.
   
  Thank in advance,
  Alireza
