Chair of Multimedia Telecommunications and Microelectronics


Damian Karwowski

Damian Karwowski


(born 1979) received his M.Sc. and Ph.D. degrees from Poznan University of Technology in 2003 and 2008 respectively. He obtained a grant from Polish State Committee of Scientific Research for the years 2006-2007 for the preparation of his doctoral thesis entitled "Advanced Adaptation Algorithms of Arithmetic Coding in Hybrid Video Compression".

Currently he is an assistant at Poznan University of Technology, a member of the Chair of Multimedia Telecommunications and Microelectronics. He is an author and co-author of several articles on digital video coding in both national and international conferences. He has been taking part in several industry-oriented projects that encompasses:

  • H.264/AVC video codec software and hardware development;
  • MPEG-4 AAC HE audio decoder DSP implementation;
  • H.263 videoconference codec DSP implementation;
  • MPEG-2 to H.264/AVC video transcoder implementation;
  • Automatic image quality improvement;
  • Optimization of video and audio codecs.
His interests are centered on image and audio compression algorithms, entropy coding techniques for digital audio and digital video, and realization of video and audio codecs on PC, DSP and FPGA platforms.
