| Abstract | The point-based registration technique of Bookstein [1] can be seen as an interpolation problem. With this technique an elastic transformation based on thin-plate splines is determinedwhich maps the source and target landmarks exactly to each other. However, in real applications the positions of the landmarks can only be determined approximately. Therefore, in this case an interpolation scheme is inadequate and should be substituted by an approximation scheme to take into account the localization errors. In this paper, we describe an approach for extending Bookstein 's method in this direction. Keywords--- Thin-Plate Splines, Regularization, Image Registration I. Thin-Plate Spline Interpolation The use of thin-plate spline interpolation as point-based elastic registration method of medical images was first proposed by Bookstein [1]. Below we briefly describe this method in the general context of d-dimensional images. The general problem can be stated as follows: Given two sets of n l... |
