Head pose estimation is recently a more and more popular area of research. For the last three decades new approaches have constantly been developed, and steadily better accuracy was achieved. Unsurprisingly, a very broad range of methods was explored statistical, geometrical and tracking-based to name a few. This paper presents a brief summary of the evolution of head pose estimation and a glim...

Virtual reality (VR) is a promising tool to study evacuation behavior as it allows experimentally controlled, safe simulation of otherwise dangerous situations. However, validation studies comparing evacuation behavior in real and virtual environments are still scarce. We compare the decision to evacuate in response to a fire alarm in matched physical and virtual environments. One hundred fifty...

In Pollard and Sag (1994) and Ginzburg and Sag (2000) phrases are either headed or non-headed, and if they are headed, there is a relation of selection between the daughters: either the head daughter selects its non-head sister(s), as in the phrases of type head-complements, or the non-head daughter selects its head sister, as in the phrases of type head-adjunct. In the non-headed phrases, by c...

We propose a novel method for pose-invariant facial expression recognition from monocular video sequences that combines stochastic and deterministic search processes. We use the simple face model called variable-intensity template, which can be prepared with very little time and effort. We tackle the two issues found in previous work on the variable-intensity template: low accuracy in head pose...
