Abstract: An information processing apparatus (2000) includes a determination unit (2020) and a notification unit (2040). The determination unit (2020) determines whether a field of view of a second camera is correct, on the basis of a first captured image (40), a second captured image (50), and relationship information (information indicating the relationship to be satisfied between a field of view of a first camera and the field of view of the second camera). In a case in which the field of view of the second camera is not correct, the notification unit (2040) notifies that the field of view of the second camera is not correct. The first camera is provided in a head-mounted display worn by a person. The second camera is provided in a part other than the head-mounted display.

Abstract: A surveillance system (1) includes an area information acquisition unit (101), a request information provision unit (102), and a participation consent reception unit (103). The area information acquisition unit (101) acquires information of a surveillance-desired area. The request information provision unit (102) provides participation request information for surveillance that is conducted by using an image capturing unit of a portable terminal in the surveillance-desired area. The participation consent reception unit (103) receives participation consent as a response to the participation request information, from the portable terminal.

Abstract: A state acquisition unit (2020) acquires a state of a monitoring target in a captured image captured by a camera (3040). A monitoring point acquisition unit (2040) acquires, from a monitoring point information storage unit (3020), a monitoring point corresponding to the state of the monitoring target acquired by the state acquisition unit (2020). The monitoring point indicates a position to be monitored in the captured image. A presentation unit (2060) presents the monitoring point on the captured image.

Abstract: An information processing apparatus (2000) includes a first analyzing unit (2020), a second analyzing unit (2040), and an estimating unit (2060). The first analyzing unit (2020) calculates a flow of a crowd in a capturing range of a fixed camera (10) using a first surveillance image (12). The second analyzing unit (2040) calculates a distribution of an attribute of objects in a capturing range of a moving camera (20) using a second surveillance image (22). The estimating unit (2060) estimates an attribute distribution for a range that is not included in the capturing range of the moving camera (20).

Abstract: An image processing system includes: a receiving unit configured to receive an input of a plurality of image frames constituting a video from an imaging apparatus; a detection unit configured to detect a feature point included in an image frame to be processed in the plurality of image frames; and an output unit configured to output an output image obtained by superimposing an image frame to be processed of an area detected as a feature point on a background image generated from at least some of a plurality of image frames.

Abstract: An information processing apparatus (2000) detects an assistance-needing-person (30) and an assister (40) present around the assistance-needing-person (30) at a surveillance target location. The detection of the assistance-needing-person (30) and the assister (40) is performed using various sensors. The information processing apparatus (2000) performs any one or more of decision as to whether or not to perform notification related to the assistance-needing-person (30) and decision of a content of the notification based on detection results of the assistance-needing-person (30) and the assister (40).

Abstract: To prevent or reduce an oversensitive change in the degree of opening of a bleed valve regulating the flow volume of a cooling air used to heat a fuel. A gas turbine includes: a compressor compressing an air; a combustor burning a fuel mixed with the air compressed by the compressor; a turbine configured to be driven by a combustion gas generated by the combustor; a heat exchanger causing the fuel to be supplied to the combustor to be heated through a cooling air bled from the compressor to be supplied to the turbine; a bleed valve regulating the flow volume of the cooling air; a first sensor measuring a fuel state value; a second sensor measuring a cooling air state value; and a control computer controlling the degree of opening of the bleed valve.

Abstract: An encryption device generates a ciphertext ct including an encryption element C in which a plaintext ? is set, an encryption element Cx in which an attribute x is set, and an encryption element F that is not to be decrypted with a decryption key skf corresponding to a policy f satisfied by the attribute x and in which the plaintext ? is set. A homomorphic computation device converts the ciphertext ct into a ciphertext ct˜ by converting, with the encryption element F, the encryption element C included in the ciphertext ct into an encryption element C˜ that can be decrypted with the decryption key skF corresponding to a policy set F acquired by a policy acquisition unit. The homomorphic computation device performs homomorphic computation g on the ciphertext ct˜ to generate a ciphertext ct*.
