Psychophysiological Assessment of Perceived Quality: Towards an Objective Measurement of Subjective Quality of Experience
Event date:  February 17, 2020 4:00 PM  to 5:30 PM

Abstract:

Due to the lack of reliable computational models, psychophysical methods are still considered the gold standard for assessing the perceptual quality of technical systems of visual communication and computing. The core of these methods is a judgment experiment: a human observer is presented with a stimulus, i.e. a distorted (or undistorted) image or video, and gives an overt response on its perceived quality. These methods are well standardized and widely used in practice. However, they inherently suffer from conceptual and practical flaws that impose certain limitations on the interpretation and the applicability of psychophysical tests.

In my talk I will describe how psychophysiological, e.g. EEG-based, methods may bypass the drawbacks of conventional quality assessment and outline avenues of research toward the objective assessment of subjectively perceived quality.

Sebastian Bosse is a senior researcher with the Machine Learning group and the Image Video Coding group in the Video Coding & Analytics Department of Fraunhofer Institute for Telecommunications – Heinrich Hertz Institute, Berlin, Germany.
He studied Electrical Engineering and Information Technology at RWTH Aachen University, Aachen, Germany and Polytechnic University of Catalonia, Barcelona, Spain. He received the Dipl.-Ing. degree in from RWTH Aachen University, Aachen, Germany and the Dr.-Ing. degree in Electrical Engineering and Computer Science from Berlin University of Technology, Germany.
As a student, Sebastian was a visiting researcher at Siemens Corporate Research, Princeton, USA. In 2014, he was a guest researcher at Stanford University, USA.
His major research interests are image and video compression, human visual perception for image communications, and neural correlates of perceived image quality and quality of experience, as well as signal processing.
