    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: Provided is an art of registration and management of the placement positions of objects to be managed can be easily and reliably performed. A device includes an identification information receiving unit 11 that receives identification information that can identify an object to be managed and acquisition time of the identification information; a position information receiving unit 12 that receives position information relating to a position of a person who moves around in a target floor while carrying equipment configured to acquire the identification information; and a placement information registration unit 13 that registers the placement information of the object to be managed by registering the position information received by the unit 12 at the same time or almost at the same time as the acquisition time of the identification information that is received by the unit 11 in association with the identification information.

    Abstract: An information processing system includes: a first input unit configured to receive an input of a video captured by each of a plurality of image capturing devices; a selection unit configured to select a different moving object that is different from a tracking-target moving object in the video captured by a first image capturing device of the plurality of video devices, from among moving objects in the video captured by the first image capturing device; and an estimation unit configured to estimate a time point at which the tracking-target moving object is to appear, based on whether or not the different moving object has appeared in the video captured by a second image capturing device of the plurality of image capturing devices.

    Abstract: An object information extraction apparatus (2000) includes an image acquisition unit (2020), a frequency determination unit (2040), and an information extraction unit (2060). The image acquisition unit (2020) acquires a plurality of images corresponding to a predetermined unit time of a video. The frequency determination unit (2040) generates frequency information for each of a plurality of partial areas included in each of a plurality of images. The information extraction unit (2060) extracts information of an object included in each partial area from each image corresponding to the number indicated by the frequency information for each partial region among a plurality of images corresponding to a predetermined unit time for each partial area.

    Abstract translation: 对象信息提取装置（2000）包括图像获取单元（2020），频率确定单元（2040）和信息提取单元（2060）。 图像获取单元（2020）获取与视频的预定单位时间相对应的多个图像。 频率确定单元（2040）为包括在多个图像中的每一个中的多个局部区域中的每一个生成频率信息。 信息提取单元（2060）从对应于每个局部区域的预定单位时间的多个图像中的每个部分区域的频率信息所指示的数量的每个图像中提取每个部分区域中包括的对象的信息。
