The Chair of Pattern Recognition (Computer Science 5) is part of the Department for Computer Sciences of the Friedrich-Alexander University of Erlangen-Nuremberg. Since its foundation in 1975 until Sep. 2005, Professor Dr.-Ing. Heinrich Niemann held the Chair; since Oct. 2005, Prof. Dr.-Ing. Joachim Hornegger is head of the chair.

"Pattern Recognition" stands for the search of an automatic transformation from samples, obtained from the environment with suitable sensors, into a symbolic description which is specific to the application. An example of a pattern recognition system is a speech dialogue system: a user can ask by telephone a computer with natural speech. The microphone (the sensor) in the telephone samples the sound waves. With algorithms, developed at our chair, the system can analyze the natural speech to get the information which is required to generate an adequate answer and present the synthesized speech to the human user. Pattern recognition deals with all aspects of the whole procedure, from data acquisition to generation of an answer. Applications of pattern recognition range from industrial image processing, recognition of handwritings, medical image processing, speech dialogue systems, computer vision to problems of control engineering. The research at the Chair for Pattern Recognition is organized according to the following fields:

• image processing
• mono- and multimodal image fusion and registration
• tomographic reconstruction
• segmentation and classification in medical image processing
  
  
• 3-D object recognition
• object tracking
• active sensor data processing
• 3-D reconstruction and camera calibration
• plenoptic modeling
• augmented reality
  
  
• autonomous mobile systems
• mimics and gestics
• speech processing
• prosody
• dialogue
• recognition of user states (angry, tired, hesitant, ...)
