DESCRIPTION:Dr. Krystian Mikolajczyk\, University of Surrey\, UK\nIn this 
 talk I will give an overview of my recent research activities at the Cente
 r for Vision\, Speech and Signal processing at the University of Surrey\, 
 UK.\nI will then talk in more detail about our  project to develop recogni
 tion software for autonomous reconnaissance robots.\nThe project consisted
  of development of a swarm of autonomous flying \nvehicles navigated via w
 ireless link and a GPS system. The UAVs acquire images which are then proc
 essed in the ground station \nby threat recognition software. Our recognit
 ion system is based on a vocabulary forest of local features. Large number
 s of features are extracted from image examples and are represented by man
 y vocabulary trees. Features from a query image are matched to the trees a
 nd vote for object categories and their locations. Large number of trees\n
 make the process efficient and robust. The system is capable of \nsimultan
 eous categorization and localization of objects. The approach\nobtains exc
 ellent performance on large test sets. We demonstrate the robustness of ou
 r method to appearance variations\, scale change\, asymmetric objects\, ba
 ckground clutter and occlusion. The system has been extended to human acti
 on recognition by incorporating motion information into local features. Th
 e performance has been evaluated on 17 challenging real action categories 
 from Olympic Games.\n\nSince 2005 Krystian Mikolajczyk is a Lecturer in Ro
 bot Vision at the \nCenter for Vision\, Speech and Signal processing at th
 e University of \nSurrey\, UK.\nHe did his PhD at INRIA Grenoble on invari
 ant interest points and then \nheld post-doc positions at INRIA\, Universi
 ty of Oxford and Technical University of Darmstadt\, Germany\, working pri
 marily of image recognition.\nHe currently leads a group of PhD students a
 nd research assistants \nfocused on visual recognition problems including 
 issues like image \ncategorization\,object and action recognition\, retrie
 val\, matching as well as image enhancement\, kernel based classifiers\, o
 nline learning etc.\n\nK. Mikolajczyk's homepage
