Les piles focales (FS) ont attiré l'attention en tant que représentation alternative du champ lumineux (LF). Cependant, le problème de la reconstruction du LF à partir de son FS est considéré comme mal posé. Bien que de nombreuses méthodes de régularisation aient été discutées, aucune méthode n’a été proposée pour résoudre parfaitement ce problème. Cet article a montré que le LF peut être parfaitement reconstruit à partir du FS via un banc de filtres en théorie pour les scènes lambertiennes sans occlusion si l'ouverture de la caméra pour acquérir le FS est une fonction de Cauchy. La simulation numérique a démontré que le banc de filtres permet une reconstruction parfaite du LF.

Abstract: Focal stacks (FS) have attracted attention as an alternative representation of light field (LF). However, the problem of reconstructing LF from its FS is considered ill-posed. Although many regularization methods have been discussed, no method has been proposed to solve this problem perfectly. This paper showed that the LF can be perfectly reconstructed from the FS through a filter bank in theory for Lambertian scenes without occlusion if the camera aperture for acquiring the FS is a Cauchy function. The numerical simulation demonstrated that the filter bank allows perfect reconstruction of the LF.
