Title (EN) PHASE RETRIEVAL
(FR) EXTRACTION DE PHASE
Abstract:
(EN) There is provided a method of processing a pixellated image to retrieve a phase distribution representative of the image. The phase distribution representative of the image is in the Fourier domain. The method comprises padding the image pixels with padding, or non-image, pixels to increase the total number of pixels in the pixellated image. The method further comprises processing the padding or non-image pixels differently to the image pixels in each iteration of the iterative method.
(FR) La présente invention concerne un procédé de traitement d'une image pixellisée destiné à extraire une distribution de phase représentative de l'image. La distribution de phase représentative de l'image se trouve dans le domaine de Fourier. Le procédé consiste à compléter les pixels de l'image avec des pixels de remplissage, ou pixels blancs, pour augmenter le nombre total de pixels de l'image pixellisée. Le procédé consiste en outre à soumettre les pixels de remplissage, ou pixels blancs, à un traitement différent de celui des pixels de l'image à chaque itération du procédé itératif.
