Orthogonal quincunx wavelets with fractional orders
We present a new family of 2D orthogonal wavelets which uses quincunx sampling. The orthogonal refinement filters have a simple analytical expression in the Fourier domain as a fu...

Cellular Automata Based Optical Flow Computation for "Just-in-Time" Applications
Real-world tasks often require real-time performances. However, in many practical cases, “just in time” responses are sufficient. This means that a system should be efficien...

A parallel/vectorized double-precision exponential core to accelerate computational science applications
Many natural processes exhibit exponential decay and, consequently, computational scientists make extensive use of e−x in computer simulation experiments. While it is common to ...
