<DIV>Hi all,</DIV> <DIV>I would like to know if iterative point set registration needs to know the corresponding points?I mean if we have 5 points in a point set in one hand and 5 other points in a another point set on the other hand ,but we don't know which point from the point set A is correspond to which point of Point set B,is it still possible to use iterative point set registration?</DIV> <DIV>Is there any filter in ITK which use leaset -squares fitting of two point set in M-D?</DIV> <DIV>Thanks</DIV> <DIV>Danny</DIV><p>
