Title
(EN) METHODS AND APPARATUS FOR IMAGE RECONSTRUCTION
(FR) PROCEDE ET DISPOSITIF DE RECONSTRUCTION D'IMAGE
Abstract
(EN)
The invention features a method and device for generating a high-resolution digital image (80) from a relatively low-resolution digital image (76) generated using a standard detector. The method includes the step of first generating a digitized image, determining a point spread function containing sub-pixels having closer spacing than the points in the digitized image, selecting a vector c, minimizing a function [psi(c)], then reconstructing the image by substituting the minimized value of c in a function F(X, Y, Z).
(FR)
L'invention concerne un procédé et un dispositif servant à générer une image numérique à haute résolution (80) à partir d'une image numérique à résolution relativement basse (76) générée au moyen d'un détecteur standard. Ce procédé consiste à générer d'abord une image numérisée, à déterminer une réponse impulsionnelle contenant des sous-pixels possédant un espacement plus rapproché que les points situés dans l'image numérisée, à sélectionner un vecteur c, à minimiser une fonction [psi(c)], puis à reconstruire l'image par substitution de la valeur minimisée de c dans une fonction F(X,Y,Z).
