Spatio-Temporal Fading Scheme for Error Concealment in Block-Based Video Decoding Systems
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 Tensor Approach for Precise Computation of Dense Displacement Vector Fields
Using the 3-dimensional structure tensor, dense displacement vector fields (DVF) can be computed with subpixel accuracy. The approach is based on the detection of linear symmetrie...
