Title: Video Quality Evaluation Techniques

Abstract:
As digital communication of television content becomes more pervasive, the long-standing problem of assessing video quality becomes particularly important. This work describes some innovative guidelines for easy and reliable determination of a quality metric that is subjectively meaningful: Mean Time Between Failures (MTBF), representing how often a typical viewer observes a noticeable visual error and a related instantaneous metric relating to the fraction of viewers that find a given video portion to be within acceptable quality levels. The value of MTBF is addressed in the context of video quality, and objective measurements that correlate well with subjective evaluations of MTBF are investigated for different video clips at bit rates in the range of 1-5 Mbps. A method for estimating the MTBF of a video sequence from objective measurements is also described.

Bio:
Nitin Suresh received his Bachelor's degree in Electrical Engineering from the Indian Institute of Technology, Madras, India, in 2001 and his Master's degree in Electrical and Computer Engineering from the Georgia Institute of Technology, Atlanta, in May, 2003, where he is now working towards a Ph.D. degree in ECE. His current research interests are in Signal Processing with emphasis on Image and Video Processing algorithms and Quality Evaluation techniques.
