In this paper, an omnidirectional camera and a movable PTZ (Pan, Tilt, Zoom) camera are utilized to the proposed indoor surveillance system. The traditional foreground-background extraction method and frame difference method are combined together in this paper; the combined method not only can ignore noises generated form background subtraction and focus on(More)
This paper presents a novel indexing architecture to support a range of smart playback functions in collaborative telemedicine systems. These functions include replaying the session from a specified point in time, replaying all the session segments controlled by a particular physician, replaying all the session segments relating to a specific medical image,(More)
In teleconsultation sessions, a critical dependency exists between the image contents and the type and sequential order of the image processing commands used by the various participants. Accordingly, for re-entrant/late users, a significant challenge exists in restoring the image contents of the teleconsultation session in such a way that all the(More)
With the widespread deployment of the Internet nowadays and the increasing power and sophistication of network communication technologies, many collaborative systems have been proposed to support users in geographically dispersed areas in transmitting and sharing multimedia data (Huang et al., 2007; Li et al., 2004; Marsh et al., 2006). One area in which(More)
Conventionally adopted medical tele-consultation systems primarily provide an interactive discussion environment for physicians. However, as medical tele-consultation systems are used for healthcare, the manageability and retrieval capabilities are of equal importance to this interactive discussion environment. A novel medical tele-consultation system with(More)
Alzheimer's disease (AD) is becoming one of the major diseases of the elderly. Traditionally, patients take questionnaires or do some balance tests for clinical evaluation. However, results with such evaluation are subjective. For more objective quantitative measurement, this paper uses an inertial-sensor-based device to measure the gait information while(More)
