Content

Please note: This Lecture is part of the Modul "Data Analysis for Quality of Experience Assessments" please register also to the lecture Data Analysis for Computer Engineering

Quality of Experience (QoE) describes the quality or “goodness” of (audio-visual) stimuli as perceived by human observers in a specific context. It allows us to assess the influence of processing steps not only with respect to the physical properties of the signal itself e.g. SNR, but also how any degradations influence the observers’ experience by taking into account the psychophysical properties of human perception.

Aim of this lecture is to introduce the concepts and applications of QoE and the corresponding algorithms and assessment methodologies, but also how QoE complements in particular multimedia signal processing. The focus will be on audio-visual stimuli in the context of telecommunication- and multimedia-related applications, systems and services.

The following topics will be covered:

  • What is QoE?
  • Basic QoE concepts
  • Subjective QoE assessment for audio-visual stimuli
  • Objective QoE assessment for audio-visual stimuli with QoE algorithms/metrics
  • Discussion of selected QoE metrics, especially for video
  • Design of QoE metrics using a data-driven approach

Selected topics will be examined in-depth during the team oriented semester project.

Course schedule

The course consists of a lecture part in block format starting before the lecture period and a tutorial/exercise part that will take place during the lecture period.

  • The lecture will take place on 10-11 April before Easter, and 19-21 April after Easter, from 10:00 to 17:30.
  • The tutorial/exercise will take place each Wednesday from 13:15-14:45.

Additionally, a separate question time will be organised on 12 May, 9 June, and 14 July for discussing issues that arise during the project phase of the overall module.
