Title: ARTICLE DISCRIMINATION SYSTEM AND CHECKOUT PROCESSING SYSTEM INCLUDING ARTICLE DISCRIMINATION SYSTEM
Abstract: [Object]To provide an article discrimination system that can accurately infer the type of an article from an article image.[Solution]An article discrimination system includes an imager, an inference component, and a setting component. The imager captures an image of an article to acquire an article image. The inference component acquires first information which the inference component utilizes to infer the type of the article from the article image and, based on the first information acquired, infers one or plural types for the type of the article from among an article type group. The setting component sets at least one of types of articles that are available and types of articles that are not available among the article type group. The inference component preferentially infers, as the type of the article corresponding to the article image, the types of articles that are available over the types of articles that are not available.
