Abstract: Provided is a data analysis device comprising: an analysis subject acquisition part for acquiring data to be analyzed (analysis subject data); a precision estimation part for estimating the analysis precision of the analysis subject data; a selection part for selecting an analysis module to be used in analyzing the analysis subject data on the basis of the result of estimating the analysis precision of the analysis subject data and information indicating the analysis time of the analysis subject data; and an analysis execution part for analyzing the analysis subject data using the analysis module having been selected by the selection part. According to this configuration, in cases where a data analysis device configures a data analysis processing method, the operator of the data analysis device does not have to preset a determination standard for configuring the processing method.

Abstract: An estimation unit of a visual object tracking apparatus estimates a plurality of estimated bounding boxes and estimated object IDs respectively corresponding to the estimated bounding boxes based on a plurality of predicted bounding boxes and a plurality of detected bounding boxes. For example, the “detected bounding boxes” are “bounding boxes (bounded areas)” detected by a detector in each of a plurality of frames in a time series such as moving images. The “bounding box” is a frame surrounding an image of an object detected in a frame. For example, the “predicted bounding box” is a “bounding box” predicted by a predictor based on an estimated bounding box(es) estimated for one or a plurality of frames in the past.

Abstract: A process of switching a provision source server of a service for a mobile object is performed at a timing suitable for a service being provided. A management system or a management apparatus evaluates a degree of influence of a server switching process of switching a provision source server of a service for a mobile object, which is exerted on the service. The management system or the management apparatus decides a timing to switch the provision source server on the basis of an evaluation result of the evaluating and gives an instruction to switch the provision source server at the timing decided by the decision.

Abstract: In an object tracking device, an object detection unit detects an object from video data using a plurality of object detection programs of different detection accuracy. The object tracking unit tracks the object from the detected position of the object by the object detection unit. The control unit controls the object detection programs used by the object detection unit based on the detection result of the object by the object detection unit and the tracking result of the object by the object tracking unit.
