Abstract—In this paper, we propose an optimal quadtree (QT)based motion estimator for video compression. It is optimal in the sense that for a given bit budget for encoding the d...

In this contribution we propose a new spatio-temporal fading scheme for block loss recovery in block-based video decoding systems. Based on a boundary error criterion obtained fro...

A key step in distributed video coding is the generation of the side information (SI) i.e. the estimation of the Wyner-Ziv frame (WZF). This step is also frequently called image i...
