Research Activity

The laboratory was founded by Tamás Szirányi for the research of image processing technologies and to develop innovative solutions for image related problems. In the last two decades the following research areas were in the focus of the laboratory: pattern recognition, biometrics, human-computer interfaces, image and video analysis, industrial applications of image processing, image and video coding, image retrieval, stereo vision, motion analysis, object and screen recognition, image processing in parallel systems (FPGAs), image and video segmentation. Members of the lab participated in several national and international research and development projects (OTKA, GOP, TAMOP, BAROSS, GVOP, NKFP, cooperations with Samsung, and Tateyama corporations). Knowledge and experiences are shared with University students during different courses such as Image Processing, Measuring image information, Biometrics and in supervised project works.

Main Research Results

Some examples of successful research results are:

  • Method for the estimation of urbanization in aerial images,
  • Hidden Markov Models for the segmentation and for unusual event detection in videos,
  • Methods for film restoration: video stabilization, blotch detection,
  • Offline handwriting recognition in archive documents,
  • Hang gesture recognition,
  • Method for the estimation of compression rate and image quality in H.264,
  • Motion detection in case of moving cameras.
