His research, in the field of intelligent systems, has been in the areas of PERCEPTION: Computer Vision (CV), Signal and Image Processing (SIP), MACHINE INTELLIGENCE: Neural Networks (NN) and Artificial Intelligence (AI), Evolutionary Computation: Genetic Algorithms and Animats, and MULTIMEDIA and VIDEO PROCESSING: Large Image Data Bases, Forensics, and Document Processing. Recent work includes joint space/spatial-frequency/temporal representations (Gabor, wavelets, and Wigner), clustering and segmentation, motion analysis, Automatic Target Recognition (ATR), Face and Gesture Recognition, Contents - Based Information Retrieval (CBIR) and Video Processing, Animats using Perception-Control-Action-Learning (PCAL) and Evolutionary Computation (EC) strategies, and Active, Functional, and Selective Perception (AFSP) and Attention. Research on topics related to joint space/spatial-frequency image representations and object/target recognition has been supported by NSF (ECS8310057, EET8713563) and DARPA (F19628-85-C-0002// CX-7401-86 / CX-7916-87 / CX-9333-88 & #MDA 972-91-C-0004), while research on face recognition and multiframe video analysis has been supported by the FBI (A004765 & JFBI92063), ARL and ARPA (DAAL01-93-R-9286).
He has been a consultant for both government (NIH, NRL, MIT Lincoln Lab/DARPA, NASA) and private industry (Honeywell, Perkin Elmer, Procter & Gamble, SAIC, and 3M). He has also cooperated with the MAYO Clinic on biomedical image processing and computer tomography (CT). He has lectured extensively in US and abroad, was an invited guest lecturer for several NATO Advanced Study Institutes (ASIs) and Advanced Research Workshops (ARWs) on Computer Vision, Pattern Recognition and Robotics, and he has taught professional short-courses on Computer Vision, Neural Networks, and AI. He was Director for the NATO Advanced Study Institutes (ASI) on "Active Perception and Robot Vision" held in 1989, in Maratea, Italy, "Statistics and Neural Networks" held in 1993, in Les Arcs, France, and "Face Recognition: From Theory to Applications" held in 1997, in Stirling, UK. He served as Co-Chair for the 13th International Conference on Pattern Recognition held in Vienna, Austria, in 1996. Member of the program and organizing committees for the 1st, 2nd and 3rd Int. Confs. on 'Automatic Face and Gesture Recognition', held in Zurich, Switzerland, 1995, Killington, VT, 1996, and Nara, Japan, 1998.
He authored over 150 scientific papers. His book "Computational Vision" was published by Academic Press in September 1990, and he is the editor of the book, "Neural Networks for Perception" (Vol 1 & 2), published by Academic Press in November 1991. He was elected IEEE Fellow, effective as of January 1, 1993, for contributions to joint spatial/spectral image representations and neural networks, and their theoretical integration and application to human and machine perception.
