Localization of Anatomical Point Landmarks in 3D Medical Images by Fitting 3D Parametric Intensity Models

We introduce a new approach for the localization of 3D anatomical point landmarks based on 3D parametric intensity models which are directly fit to the image. We propose an analytic intensity model based on the Gaussian error function in conjunction with 3D rigid transformations as well as deformations to efficiently model tip-like structures of ellipsoidal shape. The approach has been successf...

Reened Localization of Three-dimensional Anatomical Point Landmarks Using Multi-step Diierential Approaches

In this contribution, we are concerned with the detection and re ned localization of 3D point landmarks. We propose multi-step di erential procedures which are generalizations of an existing two-step procedure for subpixel localization of 2D point landmarks. This two-step procedure combines landmark detection by applying a di erential operator with re ned localization through a di erential edge...

On the Localization of 3D Anatomical Point Landmarks in Medical Imagery Using Multi-step Differential Approaches

In this paper, we investigate diierential approaches for the localization of 3D anatomical point landmarks in 3D medical images. First, we study an existing 2D edge intersection approach for localizing corners and theoretically analyze the localization accuracy of this method for an analytic model of an L-junction. Then, we extend this approach to 3D. We propose two two-step and one three-step ...
