Error concealment for spatially Scalable Video Coding using hallucination

Abstract

We propose a new error concealment method based on hallucination for Scalable Video Coding with spatial scalability. In this method, parts of the frames which lose the enhancement layer are up-sampled from base layer and "hallucinated" as concealment frames. The database for hallucination is generated from the high-resolution and low-resolution frame-pairs near the lost frames in the video sequence. The effectiveness of hallucination here lies in the similarity between the nearby frames in the video sequence. Experiments show that the proposed method has superior results over the state-of-the-art error concealment method for spatially Scalable Video Coding.978-1-4244-3828-0/09/$25.00 ©2009 IEEE

A Framework to Measure and Estimate Video Quality in SVC Real-Time Adaptive Systems

“…Proof of their importance is the large number of works studying error concealment techniques, particularly, in the SVC realm (Y. Chen et al, 2006;Lambert et al, 2009;Ma, Wu, & Sun, 2009;Park, Wang, & Ko, 2007;Pitrey et al, 2010;Pitrey et al, 2011;Stoufs et al, 2007). Among those, some ideas involve assuming a protected base layer (with FEC algorithms) as a concealment mechanism for enhancement layer losses (Pitrey et al, 2010, Pitrey et al, 2011.…”
