    Abstract: An evaluation apparatus (10) includes an acquisition unit (110), an index computation unit (120), and a suitability computation unit (140). The acquisition unit (110) acquires arrangement information and environmental information. The arrangement information indicates at least any of position, orientation and field angle of an image capturing apparatus. The environmental information indicates an environment of a target region. The index computation unit (120) computes a surveillance index by using the arrangement information and the environmental information, the surveillance index indicating difficulty or easiness of surveilling a target object. The suitability computation unit (140) computes suitability of arrangement of the image capturing apparatus indicated by the arrangement information, based on the distribution of the surveillance index in the target region.

    Abstract: A monitoring device and the like are provided which are capable of detecting an attribute change in a suspicious object that cannot be determined from the behavior of the object. An associating unit associates, among a plurality of objects detected from time-series image data, identical objects with one another. An attribute change detecting unit detects from the time-series image data a change in an attribute of at least one of the identical objects and an attendant item. A suspicious object detecting unit detects a suspicious object on the basis of the change in attribute.

    Abstract: In order to minimize the impact of a delay (if any) that occurs when a process for detecting an object from a video takes time, and thereby achieve accurate tracking, the object detection/tracking device according to the present invention is provided with: an acquisition unit which acquires a video; a tracking unit which tracks an object in the video; a detection unit which detects an object in the video; an association unit which associates the same objects that have been detected and tracked in the same image in the video; and a correction unit which corrects the position of the tracked object using the position of the detected object, from among the associated objects.
