Abstract: A position and pose determination unit (103) is configured to determine a position and an pose of the video acquisition unit (110) in such a way that a level of hiding caused by overlapping of objects becomes low based on environmental object information indicating an environmental object including a structural object present in the monitored area and a placed object placed in the structural object, and staying characteristic information indicating a staying characteristic of the object determined depending on the environmental object. The analysis and display unit (111) is configured to perform at least one of analyzing a video captured by the video acquisition unit (103) at the position and the pose determined by the position and pose determination unit (110) and displaying the video.

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: A trajectory linking apparatus capable of linking a trajectory having a feature value with a trajectory having no feature value is provided. The trajectory linking apparatus includes a feature-including trajectory linking unit and an interpolation unit. The feature-including trajectory linking unit receives trajectory information for each time segment. The trajectory information represents a plurality of trajectories indicating respective movement paths of a plurality of objects detected from image data of a respective time segment, and also indicating whether or not each of the trajectories has a feature for object re-identification. The feature-including trajectory linking unit generates a linked trajectory having a feature by linking a first trajectory having a feature with a second trajectory. The interpolation unit generates an interpolated trajectory by linking a third trajectory to the first and second trajectories.
