VIDAS: Video Assisted Audio Coding and Representation
Goals The basic objective of VIDAS was that of approaching the problem of facial animation from a combined audio-video point of view, for both the analysis and the synthesis. The main goal was the consolidation of advanced technologies for synthetic/natural representation and coding of facial sequences. In particular, a generic face-to-face communication has been modelled as a multimodal inform...

متن کاملApplications of Directional Audio Coding in Audio
Directional Audio Coding (DirAC) is a method for spatial sound representation, applicable to different sound reproduction systems. In the analysis part, the diffuseness and direction of arrival of sound is estimated in a single location depending on time and frequency. In the synthesis part, microphone signals are first divided into non-diffuse and diffuse parts, and are then reproduced using d...
متن کاملProgressive Audio Coding
1 INTRODUCTION AND MOTIVATION New technologies open the possibility of mobile computing. Wireless links allow communications while moving. Various technologies allow the use wired or wireless links to connect to LANs or WANs [RAH93], [BAB94], [KRU92], [LDH94], [TUT92]. On the other hand, multimedia applications become more and more popular. They produce a large amount of data [STN95]. In a mobi...
