This paper presents an advanced animation framework for virtual character within the MPEG-4 standard. The Bonebased Animation (BBA) specifications are described and it is shown how they extend the MPEG-4 Face and Body Animation (FBA) specifications. Specifically, the scene graph concept, the BBA nodes related to bone and muscle modeling, the animation parameters and the compression capabilities...

In the paper we present a novel method for three-dimensional scene recovering from one image of a man-made environment. We use image segmentation and perspective cues such as parallel lines in space. The algorithm models a scene as a composition of surfaces (or planes) which belong to their vanishing points. The main idea is that we exploit obtained planes to recover neighbor surfaces. Unlike p...

Spectrum agility (SA) is a novel way of improving spectrum utilization efficiency and making greater bandwidth available to network applications. Despite its advantages, the fundamental operations (e.g., periodic spectrum sensing) involved in realizing SA can also adversely affect application performance. We propose Context-Aware Spectrum Agility (CASA), which uses application hints together wi...
