Edgels and Tangent Planes in Image Warping
In this paper we first describe generally the uses of thin-plate splines for image deformation. We then go on to demonstrate why we feel that incorporating edgel information into a warp has great potential. An extension to the edgel method of Bookstein and Green (1993a,b) is outlined for use in three dimensions. Finally we give an example of the results of using this formulation for three-dimensional magnetic resonance images of the human head.
