Seminar about video quality measurements

May 7, 2012 at Kista Entré

Acreo was fortunate to be visited by one of the world’s leading experts in video quality assessment Margaret Pinson from the Institute of Telecommunication Sciences, USA. While here, she gave a two hour lecture that gave an overview of her work both past and present. Containing both subjective and objective video quality assessment, as well as covering the whole development chain to international standardization. Useful for anyone working in the field she provided many practical hints for working with video quality assessment.

You can see her presentation here.


  1. Introduction (Kjell Brunnström, Acreo)
  2. Topics on Video Quality: Tools, Techniques and Current Events (Margaret Pinson, ITS/NTIA, part 1)

  4. Topics on Video Quality: Tools, Techniques and Current Events (Margaret Pinson, ITS/NTIA, part 2)
  5. Discussion


Abstract: The talk will summarize on-going and past research at Institute for Telecommunication Sciences (ITS) into video quality; plus current news in the international standards area. The focus is on tools and techniques that you can use in your work.

  • Why objective video quality models are needed
  • Iterated Nested Least Squares Algorithm (INLSA)
  • Calibrating video
  • NTIA’s objective video quality models
  • Consumer Digital Video Library (
  • Validating objective video quality (VQEG, ITU)
  • Developing a new ITU Recommendation on audiovisual quality subjective testing
  • Collaborative efforts to develop better video quality models


Margaret H. Pinson (margaret(at) received her B.S and M.S. degrees in computer science from the University of Colorado at Boulder, in 1988 and 1990, respectively. Since 1988, she has been working as a researcher at the Institute for Telecommunication Sciences (ITS) in Boulder, Colorado. Margaret H. Pinson joined the Video Quality Program in 1989.

Mrs. Pinson is project leader of the Video Quality Research Program. Her goal is to develop automated metrics for assessing the performance of video systems and actively transfer this technology to end users, standards bodies, and U.S. industry. Mrs. Pinson is a Co-Chair of the HDTV project in the Video Quality Experts Group (VQEG) and an Associate Rapporteur of Question 12 in ITU-T Study Group 9. She has served as technical editor for VQEG Final Reports and ITU-T Recommendations. Mrs. Pinson administers the Consumer Digital Video Library. ITU Recommendations include three objective video quality metrics developed by Mrs. Pinson and other members of the Video Quality Research Program.
