Abstract[English]
The present disclosure relates to operations that include identifying a first transition-edge portion of a first image of an eye that corresponds to a transition edge of the eye. The operations may also include determining, based on first-portion pixel data corresponding to the first transition-edge portion, a first transition-edge representation of the transition edge. The operations may include identifying a second transition-edge portion of a second image of the eye that corresponds to the transition edge. In addition, the operations may include determining, based on second-portion pixel data corresponding to the second transition-edge portion, a second transition-edge representation of the transition edge. Moreover, the operations may include determining an alignment registration between the eye as depicted in the first image and the second image based on a transition-edge based registration that is based on a comparison between the first transition-edge representation and the second transition-edge representation.[French]
La présente divulgation concerne des opérations qui consistent à identifier une première partie bord de transition d'une première image d'un œil qui correspond à un bord de transition de l'œil. Les opérations peuvent également consister à déterminer, sur la base des données de pixel de première partie correspondant à la première partie bord de transition, une première représentation du bord de transition. Les opérations peuvent consister à identifier une seconde partie bord de transition d'une seconde image de l'œil qui correspond au bord de transition. De plus, les opérations peuvent consister à déterminer, sur la base des données de pixel de la seconde partie correspondant à la seconde partie bord de transition, une seconde représentation du bord de transition. De plus, les opérations peuvent consister à déterminer un alignement entre l'œil tel que représenté dans la première image et la seconde image sur la base d'un enregistrement basé sur un bord de transition, qui repose sur une comparaison entre la première représentation de bord de transition et la seconde représentation de bord de transition.
