Non-rigid Surface Registration Using Spherical Thin-Plate Splines
Accurate registration of cortical structures plays a fundamental role in statistical analysis of brain images across population. This paper presents a novel framework for the non-rigid intersubject brain surface registration, using conformal structure and spherical thin-plate splines. By resorting to the conformal structure, complete characteristics regarding the intrinsic cortical geometry can...
متن کاملFast non-rigid registration of medical images: comparing the thin-plate and biharmonic splines
The merging of multi-modal medical image data, typically used for applications such as surgical guidance and computer aided diagnosis, has become increasingly important. In particular, the speed by which such data can be registered is often crucial. This paper presents a novel approach based on fast Radial Basis Function evaluation using the thin-plate and biharmonic spline models. The new algo...
متن کاملPoint-Based Elastic Registration of Medical Image Data Using Approximating Thin-Plate Splines
We consider elastic registration of medical image data based on thin plate splines using a set of corresponding anatomical point land marks Previous work on this topic has concentrated on using interpola tion schemes Such schemes force the corresponding landmarks to exactly match each other and assume that the landmark positions are known exactly However in real applications the localization of...
متن کاملGroupwise Non-rigid Registration Using Polyharmonic Clamped-Plate Splines
This paper introduces a novel groupwise data-driven algorithm for non-rigid registration. The motivation behind the algorithm is to enable the analysis of groups of registered images; to this end, the algorithm automatically constructs a low-dimensional, common representation of the warp fields. We demonstrate the algorithm on an example set of 2D medical images, and show that we can obtain goo...
متن کاملNonrigid Registration of Medical Images Based on Anatomical Point Landmarks and Approximating Thin-Plate Splines
Previous work on nonrigid registration of medical images based on thin plate splines has concentrated on using interpolation schemes Such schemes force the corresponding land marks to exactly match each other and thus assume that the landmark positions are known exactly However in real applications the localization of landmarks is always prone to error Therefore to cope with these errors we hav...
