Blind channel estimation in MIMO-OFDM systems using semi-definite relaxation
A new blind channel estimation technique for multiple-input multiple-output orthogonal frequency-division multiplexing (MIMO-OFDM) systems is proposed. It estimates the channel pa...

A Variational Approach for Multi-valued Velocity Field Estimation in Transparent Sequences
Abstract. We propose a variational approach for multi-valued velocity field estimation in transparent sequences. Starting from existing local motion estimators, we show a variatio...

Rapid Resource-Constrained Hardware Performance Estimation
In a hardware-software co-design environment, an application is partitioned into modules. Each module is then mapped either to software or to hardware. The mapping process is driv...

Uncertainty optimization for robust dynamic optical flow estimation
We develop an optical flow estimation framework that focuses on motion estimation over time formulated in a Dynamic Bayesian Network. It realizes a spatiotemporal integration of ...
