Bio

Dr. Damian M. Lyons is an Associate Professor of Computer Science at Fordham University. Prior to this, he worked for 15 years as a researcher and research program manager in the area of Computer Vision and Robotics.  He completed his undergraduate education in Math, Engineering and Computer Science at Trinity College, University of Dublin in Ireland. He earned his Ph.D. in Computer Science from the University of Massachusetts at Amherst for research on a formal model of computation for sensory-based robotics (1986).
    He worked for many years as a researcher in the US branch of the corporate research laboratories of Philips Electronics, the European Semiconductor and Consumer Electronics giant. His work there included research in representing and analyzing robot action plans, integrating reactive/behavior-based & deliberative approaches to action planning, multimodal user interfaces, and automated video surveillance. Dr. Lyons served as project leader for Philips' research activities in Automated Video Surveillance, and later as Department head for the Video and Display Processing research department, responsible for technical leadership and funding for this diverse group. Dr. Lyons is currently the Director of Fordham’s Computer Vision and Robotics Lab, and Associate Chair for Graduate Studies in the Computer & Information Science Department.
    From 1990 through 1995, Dr. Lyons served as chair of the IEEE Robotics & Automation technical committee on assembly and task planning. He has served on numerous conference program committees, has published over 80 technical papers in conferences, journals and books, and holds 8 patents. Dr. Lyons is a member of ACM and IEEE.



Research

My research interests are in Computer Vision and Robotics, in particular for systems that operate in the same kind of dynamic and unstructured environments as humans. Previously I have worked in:
  • the integration of planning and reaction in robot systems
  • automated video surveillance, and
  • vision-based human-machine interfaces.

I am involved in two pieces of research in my role as Directory of the Computer Vision & Robotics Laboratory at Fordham:

  • Performance Guarantees for Emergent Behavior in Mobile Robot Systems
  • The objective of this research program is to develop the necessary advances in theory and software to build robot systems that can be deployed in critical environments in a safe, effective and reliablefashion. The approach in this proposal is based on understanding what ar ethe computational characteristics of the behavior-based approach to robotics. Unique characteristics include: the necessity for some form of sensory-motorstructure such as Schemas, the necessity for asynchronous methods of composing concurrent behaviors, and the conclusion that even simple behavior-based systems exhibit complex behavior when acting in a complex environment.
        We are developing a succinct formalism that captures these issues, and especially addresses the issue of modeling the complex environment. A process-based environment model is being developed, allowing a shared vocabulary (processes) between robot controller and environment model. It employs the Port Automata model as an operational semantics, and a CSP like selection of process composition operators for process description. The emergent behaviors of a robot interacting with an active and dynamic environment can be modelled and explored with this approach.

  • Multi-Sensor Fusion and Target-Tracking for Automated Surveillance
  • Target tracking in CCTV (Close-Circuit TV) surveillance involves determining which portions of an image in a CCTV video sequence corresponds to which surveillance target - where targets are typically people. The standard approaches developed for point target tracking, e.g.,MHT and JPDAF, have been applied to visual target tracking with some success. However, the information from a video sequence, even from a single camera, is much richer than from the point tracking applications with which multi-target methods originated. For this reason a crucial problem becomes the integration of multiple sensory cues, especially in cases where some cues can be misleading some of the time.
        We are studing sensory fusion modules based on the ”Rankand Fuse” (RAF) method, (doc) which is a general, efficient and easily scalable approach to sensory fusion. The RAF method considers both the spatial and temporal results from the sensory system, and offers an elegant method to provide top-down feedback from the application system to the fusion process, so that task context can be used to select a sensory fusion method appropriate for the specific task.
