Figure 1From: Inverse consistent non-rigid image registration based on robust point set matching Grid transformation of TPS and regularized TPS. (a) is a grid transformation using the regularized TPS. Circle points are source points and star points are target points, the line between two points represents the correspondence of points; (b) is a grid transformation using TPS, it can be seen that folding occurs in the deformation field, which implies that the deformation field is not topology-preserving.Back to article page
