Emotional Experience Analysis in Response to HDR and SDR content

High dynamic range (HDR) content provides a better quality of experience than the standard dynamic range (SDR) content due to a wide luminance range, enhanced contrast, and saturated colors. Emotional experience analysis while watching SDR content has been an active research area in affective computing. However, the impact of HDR content on human emotional experience is not explored. This paper presents a statistical analysis of emotional experience in response to HDR and SDR content. To this end, SDR and HDR versions of four audio-visual clips are shown to two different groups, each comprising of 20 male and 10 female subjects. Each subject's emotional experience is recorded in terms of valence, arousal, and dominance scores after watching each clip. A t-test reveals that HDR and SDR content is statistically different in valence, arousal, and dominance scores for overall and gender-based analysis. The subject ratings show that the HDR content enhances the emotional experience in terms of valence and dominance scores.
