In this paper, we propose a new Distributed Video Coding (DVC) architecture where motion estimation is performed both at the encoder and decoder, effectively combining global and local motion models. We show that the proposed approach improves significantly the quality of Side Information (SI), especially for sequences with complex motion patterns. In turn, it leads to rate-distortion gains of up...
In videoconferencing and video telephony applications operating in real time, a fluent transmission, even presenting visible errors, is often preferred over a correct but jerking transmission. This is the reason why error concealment techniques are adopted, within video codecs, to recover the transmission quality without affecting its fluency. In the framework of motion estimation based video codecs,...
