H.264/AVC inter prediction for heterogeneous computing systems
Springer (2013)H.264/AVC is the latest standard for video compression and is a significant advance, but at the expense of increasing computing needs. Recently, the progress of GPUs has attracted considerable attention because they are ... -
H.264/AVC inter prediction on accelerator-based multi-core systems
Springer (2013)The AVC video coding standard adopts variable block sizes for inter frame coding to increase compression efficiency, among other new features. As a consequence of this, an AVC encoder has to employ a complex mode decision ... -
Hierarchical approach for deriving a reproducible unblocked LU factorization
Sage (2019-03-17)We propose a reproducible variant of the unblocked LU factorization for graphics processor units (GPUs). For this purpose, we build upon Level-1/2 BLAS kernels that deliver correctly-rounded and reproducible results for ...

Householder QR Factorization With Randomization for Column Pivoting (HQRRP)
Society for Industrial and Applied Mathematics (2017)A fundamental problem when adding column pivoting to the Householder QR fac- torization is that only about half of the computation can be cast in terms of high performing matrix- matrix multiplications, which greatly ...

How deeply do we include robotic agents in the self?
World Scientific Publishing (2013)In human–human interactions, a consciously perceived high degree of self–other overlap is associated with a higher degree of integration of the other person's actions into one's own cognitive representations. Here, we ...
