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: Provided are: a covered area determination unit that determines whether or not a face area including a face of a target person captured in an image generated by imaging the target person includes a covered area that covers at least partial area of the face; a first determination unit that determines whether or not the target person is a living body by a first determination method using the image, in a case where the covered area determination unit determines that the face area does not include the covered area; and a second determination unit that determines whether or not the target person is a living body by a second determination method that uses the image and that is different from the first determination method, in a case where the covered area determination unit determines that the face area includes the covered area.

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 search starting point determination unit determines a search starting point in which there is a high presence probability of the target person at a first time based on the person information. A backward tracking unit estimates the presence probabilities of the target person at different locations at a second time before the first time based on the person information and determines an area where the presence probability is higher. A recognition unit calculates a degree of matching between the appearance information and the surveillance images in the area and determines a location at which the degree of matching is higher. A forward tracking unit tracks the candidates of the target person forward in time from the second time based on the person information and the location. A presence probability estimation unit estimates the presence probability of the target person at the first time.

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: The information processing apparatus (2000) acquires a first profile face image (10) and a first frontal face image, and generates a frontal face image (20) based on the first profile face image (10), with a face image generator (30). The face image generator (30) has been trained so as to generate the frontal face image (20) based on the first profile face image (10). The information processing apparatus (2000) performs face recognition on the generated second frontal face image (20) with comparing to the first frontal face image. As a result, it is computed a first recognition score, which indicates probability of that the generated second frontal face image (20) and the acquired first frontal face image (15) are of the same subject. The information processing apparatus (2000) performs training on the face image generator (30) using the first recognition score that is a feedback from the face recognition.
