    Abstract: An information processing apparatus (2000) includes a recognizer (2020). An image (10) is input to the recognizer (2020). The recognizer (2020) outputs, for a crowd included in the input image (10), a label (30) describing a type of the crowd and structure information (40) describing a structure of the crowd. The structure information (40) indicates a location and a direction of an object included in the crowd. The information processing apparatus (2000) acquires training data (50) which includes a training image (52), a training label (54), and training structure information (56). The information processing apparatus (2000) performs training of the recognizer (2020) using the label (30) and the structure information (40), which are acquired by inputting the training image (52) with respect to the recognizer (2020, and the training label (54) and the training structure information (56).

    Abstract: A queue analysis apparatus (2000) estimates a position and an orientation of each object (20) included in a target image (10). The target image (10) is generated by a camera (50) that captures the object (20). The queue analysis apparatus (2000) generates a queue line (40) that expresses, by a linear shape, a queue included in a queue region (30) being a region representing a queue in the target image (10), based on a position and an orientation being estimated for each object (20) included in the queue region (30).

    Abstract: An image processing system, an image processing method, and a program capable of implementing an association of a person appearing in a video image through a simple operation are provided. The image processing system includes an input device which accepts input of video images captured by a plurality of video cameras, a display screen generating unit which causes a display device to display at least one video image among the video images inputted from the input device, and a tracked person registering unit which is capable of registering one or more persons appearing in the video image displayed by the display device. When a person appears in the video image displayed by the display device, the display screen generating unit selectably displays person images of one or more persons, which are associable with the person appearing in the video image and which are registered by the tracked person registering unit, in a vicinity of the video image.

    Abstract: A people-flow-estimation device includes a person-count-estimation unit for estimating the number of people included in a partial area of an image; a crowd-direction-estimation unit for estimating the direction of a crowd in the partial area; a movement-amount-estimation unit for estimating the amount of movement in the partial area; and a generation unit for extracting a partial area where people exist from a plurality of partial areas on the basis of the number of people and generating, on the basis of the number of people, the extracted partial area, and the direction and movement amount of a crowd associated with the partial area, people's flow information relating to a people's flow representing the flow of people in the partial area.

    Abstract: At least one processor determines a person state of a crowd according to a people state control designation as designation information on a person state of people and an individual person state control designation as designation information on a state of an individual person in the people. The at least one processor generates a crowd state image as an image in which a person image corresponding to the person state determined is synthesized with previously-prepared image at a predetermined size, specifies a training label for the crowd state image, and outputs a pair of crowd state image and training label.

    Abstract: An object counting system includes an acquisition means for acquiring information of an estimation area which is a partial area of an image with which partial area a predetermined condition related to objects to be counted shown in the image are associated, the estimation area being a unit of area for estimating the number of the objects to be counted, a setting means for setting the estimation area in the image in such a manner that the estimation area indicated by the acquired information of the estimation area includes the objects to be counted which are not included in the objects to be counted in a different estimation area, and which satisfy the predetermined condition, an estimation means for estimating, in each estimation area, the number of the objects to be counted shown in the estimation area set in the image, and a computation means for computing a density of the objects to be counted in an area where predetermined areas in the estimation area are overlapped using the number of the objects to be counted that has been estimated in each estimation area.
