Title
(EN) JUDGING CHANGES IN IMAGES OF THE EYE
(FR) EVALUATION DES MODIFICATIONS D'IMAGES DE L'OEIL
Abstract
(EN)
The invention includes a computer-implemented method, system (100), and computer-readable medium having computer-executable modules for judging changes in components of an eye. The inventive computer-implemented method includes the steps of acquiring (103), displaying (107), and superimposing at least two digital images of the components of the eye. The method further includes the step of processing at least one of the digital images such that the superimposed images may be compared, and the step of flickering among the superimposed digital images. The step of acquiring the images may include the step of converting a photographic representation of the components of the eye to the digital image. The step of processing may include registering, warping, and/or aligning the digital images.

Cette invention se rapporte à un procédé réalisé par ordinateur, à un système (100) et à un support lisible par ordinateur, utilisant des modules exécutables par ordinateur pour évaluer les modifications des parties constitutives de l'oeil. Ce procédé mis en oeuvre par ordinateur consiste à acquérir (103), à afficher (107) et à superposer au moins deux images numériques des parties constitutives de l'oeil. Ce procédé consiste ensuite à traiter au moins une de ces images numériques, pour que les images ainsi superposées puissent être comparées, et à appliquer un scintillement aux images numériques superposées. La phase d'acquisition des images peut consister à convertir une représentation photographique des parties constitutives de l'oeil en image numérique. La phase de traitement peut consister à enregistrer, à déformer et/ou à aligner les images numériques.
