Geodesic Active Fields on the Sphere
Jean-Philippe Thiran, Dominique Zosso
In this paper, we propose a novel method to register images defined on spherical meshes. Instances of such spherical images include inflated cortical feature maps in brain medical imaging or images from omnidirectional cameras. We apply the Geodesic Active ...
2010Parametric free-form shape design with PDE models and reduced basis method
Gianluigi Rozza, Toni Mikael Lassila
We present a coupling of the reduced basis methods and free-form deformations for shape optimization and design of systems modelled by elliptic PDEs. The free-form deformations give a parameterization of the shape that is independent of the mesh, the initi ...
Elsevier2010Geometric Registration for Deformable Shapes
This tutorial overviews recent exciting and rapidly evolving research on registration and correspondence finding across multiple deforming shapes. We address the basic techniques of three main topic areas: <br>Pair-wise local optimization methods &l ...
The Eurographics Association2010Model-based Segmentation and Image Fusion of 3D Computed Tomography and 3D Ultrasound of the Eye for Radiotherapy Planning
Jean-Philippe Thiran, Meritxell Bach Cuadra, Subrahmanyam Venkata Ravi Mohana Sai Gorthi, Alessia Pica
For radiotherapy treatment planning of retinoblastoma in childhood, Computed Tomography (CT) represents the standard method for tumor volume delineation, despite some inherent limitations. CT scan is very useful in providing information on physical density ...
2009Dense deformation field estimation for atlas registration using the active contour framework
A key research area in computer vision is image segmentation. Image segmentation aims at extracting objects of interest in images or video sequences. These objects contain relevant information for a given application. For example, a video surveillance appl ...
EPFL2008Nonrigid medical image registration
Francisco Javier Sanchez Castro
Over the last two decades medical image processing has become a fundamental tool in medicine, and brain imaging is a paradigm thereof. The fast development of the imaging acquisition techniques allows medical staff to dispose of a variety of data coming fr ...
EPFL2008Hierarchical Image Registration with an Active Contour-Based Atlas Registration Model
Jean-Philippe Thiran, Valérie Duay, Subrahmanyam Venkata Ravi Mohana Sai Gorthi, Nawal Houhou
This paper proposes to apply the non parametric atlas registration framework we have recently developed in [6]. This technique derived from the optical flow model and the active contour framework allows to base the registration of an anatomical atlas on se ...
2008Dense Deformation Field Estimation for Atlas Registration using the Active Contour Framework
Jean-Philippe Thiran, Meritxell Bach Cuadra, Xavier Bresson, Valérie Duay
In this paper, we propose a new paradigm to carry out the registration task with a dense deformation field derived from the optical flow model and the active contour method. The proposed framework merges different tasks such as segmentation, regularization ...
INTEL2006Dense Deformation Field Estimation for Atlas-based Segmentation of Pathological MR Brain Images
Jean-Philippe Thiran, Meritxell Bach Cuadra, Valérie Duay, Benoît Macq, Mathieu De Craene
Atlas registration is a recognized paradigm for the automatic segmentation of normal MR brain images. Unfortunately, atlas-based segmentation has been of limited use in presence of large space-occupying lesions. In fact, brain deformations induced by such ...
2006Atlas-based segmentation of medical images locally constrained by level sets
Jean-Philippe Thiran, Valérie Duay, Nawal Houhou
Atlas-based segmentation has become a standard paradigm for exploiting prior knowledge in medical image segmentation. In this paper, we propose a method to exploit both the robustness of global registration techniques and the accuracy of a local registrati ...
