Title (EN) THREE-DIMENSIONAL RECONSTRUCTION BASED ON A LIMITED NUMBER OF X-RAY PROJECTIONS
(FR) RECONSTITUTION TRIDIMENSIONNELLE FONDEE SUR UN NOMBRE LIMITE DE PROJECTIONS RADIOGRAPHIQUES
Abstract:
(EN) A limited number of views or projections, e.g., two, are used to generate a reconstructed image of an object. In order to improve the quality of the image, terracing and smoothing functions are implemented. In addition, the reconstructed image may be divided into objects and background prior and the object and background can be reconstructed separately. Further, after the reconstructed image is generated threat and texture analyses of the reconstructed image may be performed.
(FR) On utilise un nombre limité de vues ou projections, deux par exemple, pour produire une image reconstituée d'un objet. Pour améliorer la qualité de l'image, on applique des fonctions d'étagement et de lissage. De plus, l'image reconstituée peut au préalable être divisée en un objet et un arrière-plan qui peuvent ensuite être reconstitués séparément. De plus, une fois l'image reconstituée, on peut en effectuer des analyses des menaces et des textures.
