Side information enhancement via texture and motion activity analysis in distributed video coding

Xianming Liu, Debin Zhao, Siwei Ma, Wen Gao, Pascal Frossard, Houqiang Li, Feng Wu, Bernd Girod, Shipeng Li, Guo Wei
2010 Visual Communications and Image Processing 2010  
This paper investigates how to exploit the artifacts constraint to enhance the quality of side information (SI) in distributed video coding (DVC).  ...  On the other hand, motion activity evaluation is used to determine artifact regions in temporal domain, and temporal local entropy difference is further employed to eliminate the effect of other factors  ...  Artifacts reduce the variation of intensities, thus decrease the entropy values. In both detail regions and smooth regions, blocks with lower local entropy are probably the artifact ones.  ...

Fractional Spaces and Conservation Laws [chapter]

Pierre Castelli, Pierre-Emmanuel Jabin, Stéphane Junca
2018 Theory, Numerics and Applications of Hyperbolic Problems I  
For strictly smooth convex flux and the one-dimensional case we detail the proof of this conjecture in the framework of Sobolev fractional spaces W s,1 , and in fractional BV spaces: BV s .  ...  Moreover, the proof expounded does not use the Lax-Oleinik formula but a generalized one-sided Oleinik condition.  ...  Again, the exponent s naturally appears to estimate the positive variation of the entropy solution u . Now, we can state the smoothing effect for entropy solutions. Theorem 1.  ...

A Framework for Non-Asymptotic Quantum Information Theory [article]

Marco Tomamichel
2013 arXiv   pre-print
The smooth entropies also satisfy duality and entropic uncertainty relations that provide limits on the power of two different observers to predict the outcome of a measurement on a quantum system.  ...  We show a strong converse statement for source coding with quantum side information, characterize randomness extraction against quantum side information and prove information theoretic security of quantum  ...  Here, two legitimate parties, Alice and Bob, try to distill a shared secret key that is independent of all wiretapped information.  ...
