Human-motion saliency in complex scenes

We present a new and original method for human motion analysis and evaluation, developed on the basis of the role played by attention in the perception of human motion. Attention is particularly relevant both in a multi-motion scene and in social interactions, when it comes to select and discern why and what to focus on. The first crucial role of attention concerns the saliency of human motion within a scene where other dynamics might occur. The second role, in social-close interactions, is highlighted by the selectivity shown towards gesture modalities both in peripheral and central vision. Experiments for both modeling and testing have been based on a dynamic 3D gaze tracker. © 2012 Springer-Verlag Berlin Heidelberg.
