Abstract

In a singular part detection system, a singular part having an arbitrary feature is detected from a captured image of a subject captured by an imaging unit by a singular part detecting unit, a singular part image with an arbitrary size is cut out from the captured image by a singular part image cutting unit such that the singular part overlaps the center of the singular part image, and a type of the singular part is identified by an identification unit using machine learning with the singular part image as an input.
