Audiovisual Quality Assessment And Prediction For Videotelephony

by Benjamin Belmudez, Audiovisual Quality Assessment And Prediction For Videotelephony Books available in PDF, EPUB, Mobi Format. Download Audiovisual Quality Assessment And Prediction For Videotelephony books, The work presented in this book focuses on modeling audiovisual quality as perceived by the users of IP-based solutions for video communication like videotelephony. It also extends the current framework for the parametric prediction of audiovisual call quality. The book addresses several aspects related to the quality perception of entire video calls, namely, the quality estimation of the single audio and video modalities in an interactive context, the audiovisual quality integration of these modalities and the temporal pooling of short sample-based quality scores to account for the perceptual quality impact of time-varying degradations.

Dimension Based Quality Analysis And Prediction For Videotelephony

by Falk Ralph Schiffner, Dimension Based Quality Analysis And Prediction For Videotelephony Books available in PDF, EPUB, Mobi Format. Download Dimension Based Quality Analysis And Prediction For Videotelephony books, This book provides an in-depth investigation of the quality relevant perceptual video space in the domain of videotelephony. The author presents an extensive investigation and quality modeling of the underlying video quality dimensions and the overall quality. The author examines the underlying quality dimensions and describes a method for subjective evaluation as well as the instrumental estimation of video quality in videotelephony. The book presents a new subjective test method in the field of video quality assessment. Further, it explains the experimental examination of the underlying video quality dimensions and the subjective-based, as well as instrumental-based quality estimation. Provides an investigation of the underlying quality dimensions of video in videotelephony; Presents insights into a new subjective test method, standardized as ITU-T Rec. P.918; Includes insights into the subjective and instrumental video quality estimation.

Neural Correlates Of Quality During Perception Of Audiovisual Stimuli

by Sebastian Arndt, Neural Correlates Of Quality During Perception Of Audiovisual Stimuli Books available in PDF, EPUB, Mobi Format. Download Neural Correlates Of Quality During Perception Of Audiovisual Stimuli books, This book presents a new approach to examining the perceived quality of audiovisual sequences. It uses electroencephalography (EEG) to explain in detail how user quality judgments are formed within a test participant, and what the physiological implications might be when subjects are exposed to lower quality media. The book redefines the experimental paradigms of using EEG in the area of quality assessment so that they better suit the requirements of standard subjective quality testing, and presents experimental protocols and stimuli that have been adjusted accordingly.

Management Of Speech And Video Telephony Quality In Heterogeneous Wireless Networks

by Błażej Lewcio, Management Of Speech And Video Telephony Quality In Heterogeneous Wireless Networks Books available in PDF, EPUB, Mobi Format. Download Management Of Speech And Video Telephony Quality In Heterogeneous Wireless Networks books, This book shows how networking research and quality engineering can be combined to successfully manage the transmission quality when speech and video telephony is delivered in heterogeneous wireless networks. Nomadic use of services requires intelligent management of ongoing transmission, and to make the best of available resources many fundamental trade-offs must be considered. Network coverage versus throughput and reliability of a connection is one key aspect, efficiency versus robustness of signal compression is another. However, to successfully manage services, user-perceived Quality of Experience (QoE) in heterogeneous networks must be known, and the perception of quality changes must be understood. These issues are addressed in this book, in particular focusing on the perception of quality changes due to switching between diverse networks, speech and video codecs, and encoding bit rates during active calls.

by Sebastian Möller, Quality Engineering Books available in PDF, EPUB, Mobi Format. Download Quality Engineering books, Der Begriff der Qualität und der Gebrauchstauglichkeit hat in der Informations- und Kommunikationstechnik sowie der Informatik eine herausragende Bedeutung. Der Autor führt in diese Thematik ein, indem er zunächst die Fachbegriffe und die Grundlagen der Psychophysik und Psychometrie erläutert. Darauf aufbauend wird der Kreislauf einer menschenorientierten Systementwicklung vorgestellt. Die Messung und Vorhersage von Qualität und Gebrauchstauglichkeit wird anhand von Beispielen veranschaulicht, u. a. für Sprach- und multimodale Dialogsysteme.
