Title: Robust sensor fusion in real maritime surveillance scenarios Author(s): García, Jesús; Guerrero Madrid, José Luis; Luis Bustamante, Álvaro; Molina, José M. Abstract: This paper presents the design and evaluation of a sensor fusion system for maritime surveillance. The system must exploit the complementary AIS-radar sensing technologies to synthesize a reliable surveillance picture using a highly efficient implementation to operate in dense scenarios. The paper highlights the realistic effects taken into account for robust data combination and system scalability.

Title: A multi-agent architecture to support active fusion in a visual sensor network Author(s): Castanedo, Federico; García, Jesús; Patricio Guisado, Miguel Ángel; Molina López, José M. Abstract: One of the main characteristics of a visual sensor network environment is the high amount of data generated. In addition, the application of some process, as for example tracking objects, generate a highly noisy output which may potentially produce an inconsistent system output. By inconsistent output we mean highly differences between tracking information provided by the visual sensors. A visual sensor network, with overlapped field of views, could exploit the redundancy between the field of view of each visual sensor to avoid inconsistencies and obtain more accurate results. In this paper, we present a visual sensor network system with overlapped field of views, modeled as a network of software agents. The communication of each software agent allows the use of feedback information in the visual sensors, called active fusion. Results of the software architecture to support active fusion scheme in an indoor scenario evaluation are presented.

Title: Analysis of distributed fusion alternatives in coordinated vision agents Author(s): Castanedo, Federico; García, Jesús; Patricio Guisado, Miguel Ángel; Molina, José M. Abstract: In this paper, we detail some technical alternatives when building a coherent distributed visual sensor network by using the multi-agent paradigm. We argue that the multi-agent paradigm fits well within the visual sensor network architecture and in this paper we specially focus on the problem of distributed data fusion. Three different data fusion coordination schemes are proposed and experimental results of passive fusion are presented and discussed. The main contributions of this paper are twofold, first we propose the use of multi-agent paradigm as the visual sensor architecture and present a real system results. Secondly, the use of feedback information in the visual sensors, called active fusion, is proposed. The experimental results prove that the multi-agent paradigm fits well within the visual sensor network and provide a novel mechanism to develop a real visual sensor network system.

Title: Ontological representation of context knowledge for visual data fusion Author(s): Gómez Romero, Juan; Patricio Guisado, Miguel Ángel; García, Jesús; Molina, José M. Abstract: Context knowledge is essential to achieve successful information fusion, especially at high JDL levels. Context can be used to interpret the perceived situation, which is required for accurate assessment. Both types of knowledge, contextual and perceptual, can be represented with formal languages such as ontologies, which support the creation of readable representations and reasoning with them. In this paper, we present an ontology-based model compliant with JDL to represent knowledge in cognitive visual data fusion systems. We depict the use of the model with an example on surveillance. We show that such a model promotes system extensibility and facilitates the incorporation of humans in the fusion loop.
