Hi Lisa,<br><br>the implementation details of the TPS is explained in the TMI Paper of Davis et al.<br><b>"A Physics-Based Coordinate Transformation<br>for 3-D Image Matching"</b><br><br>There you can find the details how the coefficients and the affine parameters are estimated based on a linear equation system solved via SVD.<br>

<br><div><br></div><div>Hi List Users,</div><div><br></div><div><br></div><div>I know I've asked this many times but I haven't got a satisfactory answer yet. The thin plate splines implementation in ITK seems really confusing, atleast to me. I tried reading the paper referenced in the implementation but that paper is on Elastic Body Splines. I went through the txx files as well. Could somebody explain the TPS implementation to me? Why cannot the TPS be used as the transform in ICP and why does the TPS require the Amoeba optimizer specifically?</div>
<div><br></div><div>Thanks a lot</div><span class="HOEnZb"><font color="#888888"><div><br></div><div>Lisa</div>
