TPS-HAMMER: Improving HAMMER registration algorithm by soft correspondence matching and thin-plate splines based deformation interpolation
We present an improved MR brain image registration algorithm, called TPS-HAMMER, which is based on the concepts of attribute vectors and hierarchical landmark selection scheme proposed in the highly successful HAMMER registration algorithm. We demonstrate that TPS-HAMMER algorithm yields better registration accuracy, robustness, and speed over HAMMER owing to (1) the employment of soft correspo...
متن کاملA Modified HAMMER Algorithm for Deformable Registration of Ultrasound Images
A new technique for elastic registration of ultrasound images is proposed and evaluated. The algorithm is fast and robust, and has potential for intra-operative applications. It is a modified version of HAMMER technique, which was developed to elastically register magnetic resonance images of brain. A general concept of attribute vectors is employed to find correspondence across images, and new...
متن کاملNon-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 کاملThin plate regression splines
I discuss the production of low rank smoothers for d ≥ 1 dimensional data, which can be fitted by regression or penalized regression methods. The smoothers are constructed by a simple transformation and truncation of the basis that arises from the solution of the thinplate spline smoothing problem, and are optimal in the sense that the truncation is designed to result in the minimum possible pe...
