Title
(EN) METHOD AND DEVICE FOR REMOVING REMANENCE IN AN INFRARED IMAGE OF A CHANGING SCENE
(FR) PROCEDE ET DISPOSITIF POUR RETIRER LA REMANENCE DANS UNE IMAGE INFRAROUGE D'UNE SCENE CHANGEANTE
Abstract
(EN) The present invention relates to a method for removing by an image processing device remanence artifacts of an image (fn) of a sequence of images, captured by an infrared image capturing device, the method comprising: - retouching a remanence zone in the image (fn) by an inpainting method in order to generate a retouched image; - generating a remanence measure for at least some pixels in the image (fn) on the basis of the retouched image; and - removing remanence artifacts from at least some pixels of the image (fn) on the basis of a remanence estimate for each of said at least some pixels, each remanence estimate being generated on the basis of the remanence measurements of a plurality of images in the sequence.
(FR) La présente description concerne un procédé pour retirer, par un dispositif de traitement d'image, des artefacts de rémanence d'une image (fn) d'une séquence d'images capturée par un dispositif de capture d'images infrarouges, le procédé comprenant : - retoucher par une méthode d'inpainting une zone de rémanence dans l'image (fn) pour générer une image retouchée; - générer une mesure de rémanence pour au moins certains pixels dans l'image (fn) sur la base de l'image retouchée; et - retirer des artefacts de rémanence d'au moins certains pixels de l'image (fn) sur la base d'une estimation de rémanence pour chacun desdits au moins certains pixels, chaque estimation de rémanence étant générée sur la base des mesures de rémanence d'une pluralité des images dans la séquence.
