Comparison of Granger Causality and Phase Slope Index
We recently proposed a new measure, termed Phase Slope Index (PSI), It estimates the causal direction of interactions robustly with respect to instantaneous mixtures of independen...

Perceptually Unequal Packet Loss Protection by Weighting Saliency and Error Propagation
We describe a method for achieving perceptually minimal video distortion over packet-erasure networks using perceptually unequal loss protection (PULP). There are two main ingredie...

2-D Ultrasound Probe Complete Guidance by Visual Servoing Using Image Moments
This paper presents a visual-servoing method that is based on 2-D ultrasound (US) images. The main goal is to guide a robot actuating a 2-D US probe in order to reach a desired cro...
