Une fonction pupillaire de l'ouverture dans les systèmes de capture d'images est théoriquement dérivée de telle sorte que l'on puisse parfaitement reconstruire une image entièrement focalisée grâce à un filtrage linéaire de la pile focale. Les filtres de reconstruction parfaite sont également conçus sur la base de la fonction pupillaire dérivée. Les filtres conçus sont invariants dans l'espace ; par conséquent, la méthode présentée ne nécessite pas de segmentation régionale. Les résultats de simulation utilisant des scènes synthétiques montrent l'efficacité de la fonction de pupille dérivée et des filtres.

Abstract: A pupil function of aperture in image capturing systems is theoretically derived such that one can perfectly reconstruct all-in-focus image through linear filtering of the focal stack. The perfect reconstruction filters are also designed based on the derived pupil function. The designed filters are space-invariant; hence the presented method does not require region segmentation. Simulation results using synthetic scenes shows effectiveness of the derived pupil function and the filters.
