Due to the latest developments in communication, computing, and
storage technologies, multimedia services and applications are being
deployed for various applications such as entertainment, health care,
smart homes, security and surveillance, and intelligent
environments. The special issue focuses on research challenges and
issues related to multimedia applications.
Scheibe et al. in their paper titled "Pose Estimation of
Rotating Sensors in the Context of Accurate 3D Scene Modeling"
present the designed calibration and pose estimation techniques for
panoramic sensor-line cameras and laser range-finders. The sensor-line
cameras for used for panoramic imaging and laser range-finders can
generate dense depth maps (of isolated surface points). The authors
combined these techniques to reconstruct 3D environments such as large
buildings.
In "A
Service-Oriented Platform for Ubiquitous Personalized Multimedia
Provisioning", Yu et al. propose a three-layer software platform,
UPmP, to support efficient development and deployment of ubiquitous
personalized multimedia services. The platform provides the core
functionalities for ubiquitous personalized multimedia provisioning
including service management, multimedia recommendation, adaptation,
and delivery.
Sandnes et al. in their paper, "Near Eyes-Free Chauffeur
Computer Interaction with Chording and Visual Text Mnemonics",
investigate a user interface interaction style for in-car user
interfaces. The users interact with the in-car computer using three
chording keys, where chording pattern sequences are derived based on
visual mnemonics. The illustrations include: an in-car multimedia
system, a mobile phone, and a GPS-navigation system.
Chen et al., "Gabor
Filter Aided 3D Ultra-sonography Diagnosis System with WLAN
Transmission Consideration", investigate 3D inter-pixel
correlations instead of 2D features. Gabor filters provide a
multi-resolution representation of texture, which increases ultrasound
technology capability in the differential diagnosis of solid breast
tumors. The physicians can use the proposed diagnostic system using
hand-held devices in the hospital. They also investigate the
transmission control strategies that adapt to the time varying
wireless network conditions.
In the paper, "Cross Layer
Optimization for Data Gathering in Wireless Multimedia Sensor Networks
within Expected Network Lifetime", Shu et al. investigate
efficient gathering of multimedia data in WSNs within an expected
lifetime. They propose an adaptive scheme to adjust the transmission
radius and data generation rate by considering the interaction among
physical, network and transport layers.
Azzedin in the paper titled "Classifying and
Tracking Free Riders in Multimedia-Based Systems" addresses the
problem of free riding in decentralized collaborative environments, by
proposing a novel taxonomy of free riders in multimedia systems based
on trustworthiness. Further, a new mechanism to filter out and isolate
free riders is also proposed, simulated, and evaluated for multimedia
systems.
