An information processing system, which determines a partial area used in an erectness determination which determines whether a determination target image is erect based on a determination feature in the partial area in an image having a predetermined format and a position of the partial area in a state in which the image having the predetermined format is erect, includes processor to receive input of a plurality of learning images having the predetermined format, extract area common to the plurality of learning images in an erect state as a candidate for the partial area, determine common area reliability indicative of a degree to which the candidate for the partial area is suitable as the partial area used in the erectness determination, and determine the partial area used in the erectness determination from the candidate for the partial area, based on the common area reliability.

Information processing system, area determination method, and medium

An information processing apparatus includes a processor to store a determination feature in a predetermined partial area in an image having a predetermined format and a position of the partial area in a state in which the predetermined format image is erect, and determine whether a feature corresponding to the determination feature is present at a position in an at least one input determination target image corresponding to the position of the partial area in the predetermined format image to thereby determine whether the determination target image is erect.
