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. ...

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. ...
