With the rapid development and wide spread of the virtual reality technology, we can easily find VR systems in various places such as school, library and home. Translation and rotation, the most frequently used gestures for manipulating objects in the real world, need to be implemented in order to make a user feel comfortable while manipulating 3D objects(More)
Robust detection and tracking in a smart environment have numerous valuable applications. In this paper, an adaptive sensor fusion method which automatically compensates for bias between a laser scanner and video camera is proposed for tracking multiple people. The proposed system comprises five components: blob extraction, object tracking, scan data(More)
With the recent development of hardware technologies, vision sensor networks (VSNs) are widely deployed to communicate with environments. One of the key issues in a VSN is to build a topology graph and localize vision sensors in the network precisely and dynamically. This paper proposes a framework for estimating a topology graph for a VSN in a dynamic(More)
