Abstract
(EN)
The present disclosure proposes an apparatus for assessing the bone age of a tooth. The apparatus, according to the present disclosure, may: obtain a plurality of first tooth images of each of a plurality of teeth corresponding to a first gender and having a first bone age; pre-process each of the plurality of first tooth images, thereby generating each of a plurality of pre-processed images; train a neural network model by using the plurality of preprocessed images, thereby deriving an assessment filter for assessing the shape of a tooth of the first bone age of a human body according to the first gender; obtain a second tooth image captured of a tooth of a human body according to a second gender and gender information indicating the second gender; and derive, on the basis of the assessment filter, a second bone age of the tooth corresponding to the second tooth image, from the second tooth image and the gender information based on the assessment filter.

La présente invention concerne un appareil pour évaluer l'âge osseux d'une dent. L'appareil, selon la présente invention, peut : obtenir une pluralité de premières images de dent de chacune d'une pluralité de dents correspondant à un premier sexe et ayant un premier âge osseux; prétraiter chaque image de la pluralité de premières images de dent, en générant ainsi chaque image d'une pluralité d'images prétraitées; entraîner un modèle de réseau neuronal en utilisant la pluralité d'images prétraitées, ce qui permet de dériver un filtre d'évaluation pour évaluer la forme d'une dent du premier âge osseux d'un corps humain conformément au premier sexe; obtenir une seconde image de dent capturée d'une dent d'un corps humain conformément à un second sexe et des informations de sexe indiquant le second sexe; et déduire, sur la base du filtre d'évaluation, un second âge osseux de la dent correspondant à la seconde image de dent, à partir de la seconde image de dent et des informations de sexe basées sur le filtre d'évaluation.
