    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 group specification apparatus includes: a first group candidate setting unit that selects a person from among persons within a first shot image and sets a first group candidate, based on a spatial condition and a state condition with reference to the selected person; a second group candidate setting unit that selects a person from persons within a second shot image having a different shooting time from the first shot image, using an attribute of the person selected and sets a second group candidate, based on the spatial condition and the state condition; a similarity calculating unit that compares first attribute configuration information about the first group candidate with second attribute configuration information about the second group candidate, and calculates a similarity between the group candidates; and a group specifying unit that specifies the persons constituting the first group candidate as one group according to the similarity.

    Abstract: A flow-rate information output apparatus (2000) computes the number of objects (20) passing through a surveillance location (30) included in a target image (10) with respect to each of a plurality of surveillance directions (34). The flow-rate information output apparatus (2000) generates, with respect to one or more surveillance directions (34), a flow rate mark (40) relevant to the number of objects (20) passing through the surveillance location (30) toward the surveillance direction (34). The flow-rate information output apparatus (2000) generates a result image (60) by superimposing the flow rate mark (40) on an image including the surveillance location (30).

    Abstract: A surveillance system (1) includes an area information acquisition unit (101), a position information acquisition unit (102), a candidate determination unit (103), and a notification unit (104). The area information acquisition unit (101) acquires information of a surveillance-desired area. The position information acquisition unit (102) acquires pieces of position information of a plurality of portable terminals (20), each portable terminal performing surveillance using an image capturing unit. The candidate determination unit (103) determines a candidate portable terminal (20) to be moved to the surveillance-desired area from among the plurality of portable terminals (20) based on the acquired pieces of position information of the plurality of portable terminals (20). The notification unit (104) outputs a notification to the candidate portable terminal requesting to move to the surveillance-desired area.

    Abstract: An image processing device (3000) comprises an input unit (3020) and a presentation unit (3040). The input unit (3020) accepts an input of an operation for movement, on a captured image captured by a camera, of a first image which is superimposed on the captured image on the basis of a predetermined camera parameter indicating the position and attitude of the camera and which indicates a target object having a predetermined shape and a predetermined size set in a real space. The presentation unit (3040) presents the first image indicating the target object in a manner of view corresponding to a position on the captured image after the movement on the basis of the camera parameter.
