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.

Biography of the Head of the Laboratory

László Czúni received his MSc degree in Computer Engineering in 1996 and his PhD in image processing in 2001. Now he is an associate professor and vice dean at the Faculty of Information Technology, University of Pannonia. His teaching activity and research interests cover several areas of image processing and pattern recognition. He has published more than 50 papers at international conferences and journals. He is the author and co-author of three Hungarian lecture notes and three international patents. He is a member of the governing board of the Hungarian Association for Image Processing and Pattern Recognition (KÉPAF), and the head of the Image Processing Research Laboratory since 2012.
