An implemented system for achieving high level situation awareness about traffic situations in an urban area is described. It takes as input sequences of color and thermal images which are used to construct and maintain qualitative object structures and to recognize the traffic behavior of the tracked vehicles in real time. The system is tested both in simulation and on data collected during test...
In this paper, we describe Envelope, an adaptive, symbolic, and hybrid cognitive architecture. Envelope integrates reactive and skill-based human behavior, which relies primarily on working memory, with conscious and knowledge-based problem-solving behavior, which relies heavily on long-term memory. Envelope relaxes various lower-level psychological constraints and becomes logically omniscient in...
Most of studies in the field of information fusion focus on the production of high-level information from low-level data. The challenge is then to fuse this high-level information to produce a global and coherent information. Another approach consists in interpreting data as high-level information and fuse it at once. Our approach relies on the use of conceptual graphs model. The model is widely used...
This paper serves both as introduction to and motivation for the panel, and as a position paper to highlight retrospectives and perspectives on issues and challenges of levels 2/3 fusion implementations by presenting an independent annotated point of view.
