The most recent network technologies are enabling a variety of new applications, thanks to the provision of increased bandwidth and better management of Quality of Service. Nevertheless, telemedical services involving multimedia data are still lagging behind, due to the concern of the end users, that is, clinicians and also patients, about the low quality(More)
—In this paper, an Unequal Error Protection (UEP) scheme for the transmission of 3-D (Three-Dimensional) video over WiMAX communication channel is proposed. The colour plus depth map stereoscopic video is coded with backward compatibility using a Scalable Video Coding (SVC) architecture, where users with conventional video decoders/receivers can receive the(More)
The timely deployment of three-dimensional (3-D) video applications requires accurate objective quality measures, so that time consuming subjective tests can be avoided. Investigated is the correlation between subjective and objective evaluations of colour plus depth map 3-D video. Subjective tests are performed to determine the overall image quality and(More)
In the near future, certain 2D (2 Dimensional) video application scenarios are likely be replaced by 3D (3 Dimensional) video, in order to achieve a more involving and immersive representation of visual information, and to provide more natural methods of communication. Stereoscopic video is the simplest form of 3D video, which renders two slightly different(More)
—New 3D video applications and services are emerging to fulfill increasing user demand. This effort is well supported by the increasing 3D video content including user generated content (e.g., through 3D capture/display enabled mobile phones), technological advancements (e.g., HD 3D video capture and processing methods), affordable 3D displays, and(More)
Immersive media content provides a more natural representation of real world information compared to conventional two-dimensional video. In the near future, video applications will be replaced by immersive media with the technological advancements of three-dimensional video capture technologies, efficient multi-view compression algorithms, ever increasing(More)
Enabling 3D video in e-health applications results in the provision of more natural viewing conditions and improved diagnosis. Recent advances in wireless communications, network technologies and 3D video capture/display mechanisms enable the replacement of 2D video applications of current healthcare services with 3D video, to provide improved perception(More)
