[Insight-users] proble with iterative pointset registration 2

[Alireza Salamy]

Hi all users,
  I try to implement iterative closestpoint2 with two pointsets which are consisted of four points on each sets,but I face a problem which is:
   
  vnl_least_squares_function: WARNING: unknowns(6) > residuals(4)
vnl_levenberg_marquardt: Number of unknowns(6) greater than number of data (4)
Solution = [0, 0, 0, 0, 0, 0]
   
  Is there any way to remove this problem?Shall I just change the optimizer since I don't have any more points?
  Thanks,
  Alireza
