Abstract: [Problem] To provide a motion condition estimation device, a motion condition estimation method and a motion condition estimation program capable of accurately estimating the motion condition of monitored subjects even in a crowded environment. [Solution] A motion condition estimation device according to the present invention is provided with a quantity estimating means 81 and a motion condition estimating means 82. The quantity estimating means 81 uses a plurality of chronologically consecutive images to estimate a quantity of monitored subjects for each local region in each image.

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 object tracking device, method and non-transitory computer-readable storage medium are disclosed. An object tracking device may include an input terminal configured to receive an input image, and at least one processor connected to the input terminal wherein the at least one processor is configured to store a past state of a target object in a past image, detect a first object which is moving in the input image, detect a second object which is resting in the input image, estimate a current state of the target object based on the past state of the target object, wherein the current state comprises a current moving state when the target object is currently moving in the input image, and wherein the current state comprises a current resting state when the target object is currently resting in the input image, determine whether to prioritize tracking the target object with information corresponding to the first object or with information corresponding to the second object based on the current state of the target object.

Abstract: An information display apparatus includes: a collation unit that specifies a position of an object in an overhead image obtained by capturing an image of a region that includes the object before a disaster, based on a result of collating the overhead image with a section in a target image that includes a situation of the object after the disaster, the section satisfying a criterion for determining that an influence of the disaster is small; and a display unit that displays an image that includes the situation of the object and information by which the position of the object in the overhead image can be specified.

Abstract: Provided is a technique for enhancing operability of a mobile apparatus. An information processing apparatus (2000) includes a first processing unit (2020), a second processing unit (2040), and a control unit (2060). The first processing unit (2020) generates information indicating an event detection position in accordance with a position on a surveillance image set in a first operation. The first operation is an operation with respect to the surveillance image displayed on a display screen. The second processing unit (2040) performs a display change process with respect to the surveillance image or a window including the surveillance image. The control unit (2060) causes any one of the first processing unit (2020) and the second processing unit (2040) to process the first operation on the basis of a second operation.

Abstract: To provide an image processing system, an image processing method, and a program, capable of detecting a group with high irregularity. An image processing system is provided with: a group detector that detects a group based on an input image captured with an image capturing at a first time; a repeating group analyzer that determines that a detected group has been previously detected; and an alert module that reports when the detected group has been determined by the repeating group analyzer to have been previously detected.

Abstract: A similarity computation unit (130) derives a first probability P indicating that a first moving body appearing in the first video is the same as a second moving body appearing in the second video on the basis of similarity of feature value of the moving bodies. A non-appearance probability computation unit (140) derives a second probability Q indicating that the first moving body is not the same as the second moving body on the basis of an elapsed time after the first moving body exits from the first video. A person determination unit (150) determines whether the first moving body is the same as the second moving body by comparing the probability P and Q.
