Video Surveillance

Object Detection under Varying Illumination

The goal is to detect moving objects under background changes. We are researching about background modeling which is effective for illumination changes and motion changes such as movements of trees and water surface. To realize low cost and high performance background model, we are also researching about a new framework for modeling scene changes and for selecting the most effective model for each scene.

Wide-area Object Tracking

We are researching about object tracking in the wide area where many sensors are arranged distributedly, such as a shopping mall and a town.
The connection among the sensors is automatically estimated by using the tracking results in each sensor. As with the number of sensors, many computers are required for the wide area tracking.
Therefore, with the view of load balancing and accuracy enhancement, we are also researching about estimating automatically an optimal sensor assignment for each computer.

Sensing Web

Various kinds of sensors have been arranged on the street, in the buildings, the roads and so on. We are researching about “the disclosure of sensing information” to utilize the sensing information for a number of applications.
Each sensor is used independently for each purpose. If such sensors are linked each other through the network, we can create new values for people by combining the information of the sensors.
