Thin Plate Spline Approximation for Image Registration
نویسندگان
چکیده
The point based registration technique of Book stein 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 land marks exactly to each other However in real applications the positions of the landmarks can only be determined ap proximately Therefore in this case an interpolation scheme is inadequate and should be substituted by an approxima tion scheme to take into account the localization errors In this paper we describe an approach for extending Book stein s method in this direction

Transformation Functions for Image Registration
This paper presents a survey of past transformation functions for image registration and introduces a new transformation function for registration of images containing rigid as well as nonrigid regions. Included in the survey are similarity transformation, linear transformation, and nonlinear transformation. Nonlinear transformation itself includes thin-plate splines, radial basis functions, ap...
متن کاملLandmark and Intensity-Based, Consistent Thin-Plate Spline Image Registration
Landmark-based thin-plate spline image registration is one of the most commonly used methods for non-rigid medical image registration and anatomical shape analysis. It is well known that this method does not produce a unique correspondence between two images away from the landmark locations because interchanging the role of source and target landmarks does not produce forward and reverse transf...
متن کاملMultimodal Image Registration applied to Magnetic Resonance and Ultrasound Prostatic Images. (Recalage multimodale [i.e. multimodal] d'images de résonance magnétique et échographiques de la prostate)
This thesis investigates the employment of different deformable registration techniques to register pre-operative magnetic resonance and inter-operative ultrasound images during prostate biopsy. Accurate registration ensures appropriate biopsy sampling of malignant prostate tissues and reduces the rate of re-biopsies. Therefore, we provide comparisons and experimental results for some landmarka...
متن کاملOptic Flow Computation Using Interpolating Thin-Plate Splines
Optic flow computation is one of the most fundamental problems in the realm of visual motion. In this contribution, we present a novel optic flow computation method based on a thin-plate spline representation of image brightness data. Using a spline-based description of image brightness data removes the need for presmoothing and provides an algebraic means to compute the optic flow (explicitly)...
