Challenges for Fixed and Free-viewpoint Video Using Mobile Devices

Speaker: Professor Ricardo L. de Queiroz 

Host Faculty: Professor Nasir Memon

Abstract

Video transmission usually demands large computational capacity, be it for compression, decompression or for other actions such as view synthesis and depth estimation. Mobile devices, in the other hand, typically possess less capable processors in order to save battery reserves. A few issues are discussed and results are presented on: scalable computing codecs and RDC optimization; Wyner-Ziv transcoders for real time transmission from mobile to mobile; mixed resolution video coding for reduced complexity; and free-viewpoint television architecture and resource allocation using mobile cameras and/or mobile receivers.
