Title
(EN) METHOD FOR ASSESSING ORAL HEALTH USING A MOBILE DEVICE
(FR) PROCÉDÉ D'ÉVALUATION DE LA SANTÉ BUCCALE AU MOYEN D'UN DISPOSITIF MOBILE
Abstract
(EN)
A method for remotely assessing oral health of a user of a mobile device by obtaining, using the mobile device (40), at least one digital image (1) of said user's (30) oral cavity (31) and additional non-image data (2) comprising anamnestic information about the user (30). The digital image (1) is processed both using a statistical object detection algorithm (20) to extract at least one local visual feature (3) corresponding to a medical finding related to a sub-region of said user's oral cavity (31); and also using a statistical image recognition algorithm (21) to extract at least one global classification label (4) corresponding to a medical finding related to said user's oral cavity (31) as a whole. An assessment (10) of the oral health of said user (30) is determined based on the local visual feature(s) (3), the global classification label(s) (4) and the non-image data (2).

Procédé d'évaluation à distance de la santé buccale d'un utilisateur d'un dispositif mobile par l'obtention, à l'aide du dispositif mobile (40), d'au moins une image numérique (1) de la cavité buccale (31) dudit utilisateur (30) et de données supplémentaires de non-images (2) comprenant des informations anamnestiques concernant l'utilisateur (30). L'image numérique (1) est traitée à l'aide d'un algorithme de détection d'objet statistique (20) pour extraire au moins une caractéristique visuelle locale (3) correspondant à un constat médical associé à une sous-région de la cavité buccale (31) dudit utilisateur; et à l'aide d'un algorithme de reconnaissance d'image statistique (21) pour extraire au moins une étiquette de classification globale (4) correspondant à un constat médical associé à la cavité buccale (31) dudit utilisateur dans son ensemble. Une évaluation (10) de la santé buccale dudit utilisateur (30) est déterminée sur la base de la ou des caractéristiques visuelles locales (3), de la ou des étiquettes de classification globale (4) et des données de non-image (2).
