Patrick Kelly is the Group Leader for the Information Sciences Group (CCS-3) at Los Alamos National Laboratory. This multidisciplinary group develops computational methods necessary for understanding highly complex data sets and the behavior of large-scale discrete systems. Activities involve all aspects of tool development, from basic research in the fundamental mathematical and algorithmic underpinnings for data analysis, to the creation of end-user software products for a variety of application areas.   Patrick has spent much of his career developing algorithms and software libraries for image processing and pattern recognition. Some of his previous projects included the development of algorithms for document image analysis (automated segmentation, script identification), satellite image analysis (tracking urban growth), document retrieval (N-gram representations and analysis), and content-based retrieval systems for image databases. His current research interests include object tracking for video surveillance, methods for knowledge capture, and agent-based modeling.
