Dear all, I am trying to use LandmarkDisplacementFieldSource to compute a displacement field from 2 point sets. Although the 2 point sets are aligned almost perfectly with thin plate spline - Robust point matching algorithm (TPS-RPM), the resulting displacement field looks simply wrong. For example, the displacement field has a high value where I don´t expect any deformation/displacement. Does anybody knows the mathematical background of the itk implementation of LandmarkDisplacementFieldSource? Could anybody tell me the paper? Does any body knows how many landmarks is meaningful? best, Siming _____________________________________ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Kitware offers ITK Training Courses, for more information visit: http://www.kitware.com/products/protraining.php Please keep messages on-topic and check the ITK FAQ at: http://www.itk.org/Wiki/ITK_FAQ Follow this link to subscribe/unsubscribe: http://public.kitware.com/mailman/listinfo/insight-users
