A nonlinear quality of experience model for high dynamic spatio-temporal mulsemedia

Jalal, Lana, Murroni, Maurizio·2017·2017 Ninth International Conference on Quality of Multimedia Experience (QoMEX)

Abstract

In multimedia, quality of experience (QoE) accounts for the degree of delight or annoyance of the user of an application or service. Although humans have five senses, only two of these senses (i.e., sight and hearing) are stimulated by traditional multimedia contents. Therefore, the research efforts try to provide realistic media contents to the users. Realistic media contents are media with multiple sensorial effects, called mulsemedia, aimed at increasing user's experience through the five senses representation. This introduces a number of new issues, such as the QoE assessment for audiovisual sequences enriched with additional sensory effects such as light, wind, vibration, scent. QoE evaluation is based on mean opinion score (MOS) subjective tests measurement campaigns, which are time consuming, although allowing for the definition of statistical prediction models. The state of the art of QoE model for mulsemedia is based on parametric models. A linear model has been proposed, based on least square (LS) parameter estimation and validated on high dynamic spatio-temporal mulsemedia. This paper proposes a nonlinear model for predicting the QoE for high dynamic spatio-temporal mulsemedia. The parameter estimation relies on metaheuristic particle swarm optimization (PSO) which has been efficiently applied to optimization of nonlinear problems. A comparative analysis of the performance of the proposed model with the state of the art linear model for the QoE has been carried out based on the same MOS data set and assesses the effectiveness of the former with respect to the latter in case of high dynamic spatio-temporal mulsemedia.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
