Towards High-Level Human Activity Recognition through Computer Vision and Temporal Logic
Most approaches to the visual perception of humans do not include high-level activity recognitition. This paper presents a system that fuses and interprets the outputs of several c...

Time-Delayed Correlation Analysis for Multi-Camera Activity Understanding
We propose a novel approach to understanding activities from their partial observations monitored through multiple non-overlapping cameras separated by unknown time gaps. In our...

Active estimation of distance in a robotic system that replicates human eye movement
In a moving agent, the different apparent motion of objects located at various distances provides an important source of depth information. While motion parallax is evident for la...
