Abstract: An image processing device includes a receiver configured to receive a plurality of images of a subject from a camera; and a processor configured to: calculate, for each of the plurality of images, an angle difference between a gaze angle and a head angle of the subject to obtain a series of angle differences; and determine an authenticity of the subject at least based on the series of angle differences.

Abstract: An image processing device according to an aspect of the present invention includes: at least one memory storing a set of instructions; and at least one processor configured to execute the set of instructions to: extract a cluster image including a cluster of particles from a particle image; estimate particle density of the cluster image; determine numbers based on the particle density, and synthesize a second dictionary image from first dictionary images having densities each being equal to the numbers, the first dictionary images being images of particles of which positions is obtained; match the second dictionary image with the partial image, and determine positions of particles in the cluster image based on a result of the matching and the positions of particles of the first dictionary images; and output the determined positions of particles.

Abstract: A determination device includes a partial image acquisition unit that repeatedly acquires a partial image of a target image until a predetermined end condition is established, a score calculation unit that calculates a score related to the presence or absence of processing of the partial image in each time the partial image acquisition unit acquires the partial image, and a processing determination unit that determines the presence or absence of processing of the target image on the basis of the score.

Abstract: An information processing apparatus includes: an acquisition unit that obtains a plurality of person images which are generated by imaging a target by using a plurality of different lighting conditions, respectively; a correction unit that performs a correction process of correcting a luminance value of at least one of the plurality of person images, by using at least one of a first index value indicating a mean of a luminance value of at least one of the plurality of person images, and a second index value indicating a degree of variation in the luminance value of the at least one of the plurality of person images; and a determination unit that determines whether or not the target pretends to be another person, on the basis of the person image in which the luminance value is corrected.
