Interests & projects

• Monk is our continuous project for allowing access to historical Dutch archives which are difficult to access by means of traditional OCR approaches due to their special fonts or handwritten style. Since 2009, Monk is one of the demonstrators in the Target project
• Ubbo Emmius' RERUM FRISICARUM HISTORIA (1616) Machine-print OCR on an important historical book (a GUF grant with Zweder von Martels & Arnold Meijster)
• NWO/Morph: Learning to learn: An Adaptive Reading System using a High-Performance Morphed-Image Correlator
  dr. Marius Bulacu, dr. Arnold Meijster; Hado van Hasselt & dr. Marco Wiering
• NWO/CATCH, sub project Scratch (SCRipt Analysis Tools for the Cultural Heritage): Historical document analysis, together with the Nationaal Archief.
  Tijn van der Zant; dr. Sveta Zinger & prof. dr. John Nerbonne
• Biologically inspired image features (Poggio/Serre) are strong in whole-word recognition
• Off-line writer identification
  • NWO/ToKeN TriGraph:
    Axel Brink; Ralph Niels & dr. Louis Vuurpijl
  • The hinge transform for writer identification, by Bulacu & Schomaker (2003; 2007).
  • The allographic fraglet codebooks for writer identification, by Schomaker & Bulacu (2004).
• Our recognizer of mixed-styles online handwriting
  • ... as used in the Scryption museum (2000).
  • Handwriting recognition (on-line cursive) at NICI until 2001
• Methods: Neural networks, SVMs, Multiple agents, Genetic algorithms, finding proper distance measures for nearest-neighbour search
• Multiple-agent approaches to pattern recognition problems (project MAPR)
• Content and object-based image search
• Brain-Computer Interfacing
• Autonomous Systems / camera-based text detection by robots
