Título: | Simultaneous correspondence and non-rigid 3D reconstruction of the coronary tree from single X-ray images |
Autor: | Serradell, Eduard CSIC; Romero, Adriana; Leta, Rubén; Gatta, Carlo; Moreno-Noguer, Francesc CSIC ORCID | Fecha de publicación: | 2011 | Editor: | Institute of Electrical and Electronics Engineers | Citación: | IEEE International Conference on Computer Vision: 850-857 (2011) | Resumen: | We present a novel approach to simultaneously reconstruct the 3D structure of a non-rigid coronary tree and estimate point correspondences between an input X-ray image and a reference 3D shape. At the core of our approach lies an optimization scheme that iteratively fits a generative 3D model of increasing complexity and guides the matching process. As a result, and in contrast to existing approaches that assume rigidity or quasi-rigidity of the structure, our method is able to retrieve large non-linear deformations even when the input data is corrupted by the presence of noise and partial occlusions. We extensively evaluate our approach under synthetic and real data and demonstrate a remarkable improvement compared to state-of-the-art. | Descripción: | Trabajo presentado al ICCV 2011 celebrado en Barcelona del 6 al 3 de noviembre. | Versión del editor: | http://dx.doi.org/10.1109/ICCV.2011.6126325 | URI: | http://hdl.handle.net/10261/96869 | DOI: | 10.1109/ICCV.2011.6126325 | Identificadores: | doi: 10.1109/ICCV.2011.6126325 isbn: 978-1-4577-1101-5 |
