BOLUS ALIMENTAIRE ARTIFICIEL POUR APPRENTISSAGE DE FONCTION DE MASTICATION, BOLUS ARTIFICIEL POUR ÉVALUATION DE FONCTION DE MASTICATION, ET SYSTÈME DE GESTION D'ÉVALUATION DE FONCTION DE MASTICATION L'UTILISANT
[Problem] To provide a masticatory-function evaluation and management system capable of quickly counting "fine particles having been not crushed and ground finely" and quickly quantifying masticatory efficiency using photographic data of an artificial food mass in a stretched state, and capable of managing the masticatory efficiency quantified using such an artificial food mass for masticatory function evaluation along the time series. [Solution] When image data of an artificial food mass, in a stretched state, for masticatory function evaluation is received, the image data being transmitted from a user terminal, the number of fine particles having a spherical shape is counted from among all fine particles present in the image data, and masticatory efficiency is calculated on the basis of the number of the fine particles having the spherical shape.
