CONFERENCE PROCEEDINGS FREE ACCESSWe experimentally evaluated the influence of high and standard dynamic ranges on physiological and psychological state during video contents viewing on a 58-inch 4K TV. As the measurements items, subjectivity assessment, blinking rates, heart rate variability（the level of sympathetic nerve activity: LF/HF）, near-infrared spectroscopic (NIRS) topography were adopted. The results showed that the scores for “presence,”“feeling of depth,” “impact,”and“high quality,” when viewing 4K-HDR video content were significantly higher than those for 4K-SDR content, although the effects varied somewhat according to content. Moreover, the results indicate that 4K-HDR viewing amplify the effects of psychological states, although NIRS(O2Hb), representing nervous system activity, when viewing 4K-HDR video content, was higher than those for 4K-SDR content in some case, and NIRS when viewing 4K-HDR video content, was lower than those for 4K-SDR content in another case.View full abstractDownload PDF (642K) -

CONFERENCE PROCEEDINGS FREE ACCESSShadow detection techniques which can be applied to outdoor images are proposed. By considering photometrical and geometrical model of outdoor scenes, the positions where intensity changes sharply in image can be a good feature to separate shaded background from foreground. In this paper, we show how to evaluate the feature, how to estimate the recent status of shadow, and how to determine the shadow regions. Experiments show the effectiveness of proposed method.View full abstractDownload PDF (1036K) -

CONFERENCE PROCEEDINGS FREE ACCESSFTV (Free-viewpoint Television) enables users to view a 3D scene by freely changing the viewpoint. FTV is the ultimate 3DTV with an infinite number of views and ranks as the top of visual media in the world. MPEG has been developing FTV standards since 2001. As the third phase of FTV, the current MPEG-FTV targets revolutionized 3D viewing by super multiview, free navigation and 360-degree 3D. As for super multiview and free navigation, “Call for Evidence” to verify the existence of new technology was successfully completed and preparation of “Call for Proposals” started. FTV framework based on MVD (Multi-view plus depth) and MVS (Multi-view plus surface) 3D scene representations, and progress of FTV standardization are presented. Furthermore, 3D technology at SIGGRAPH 2016 are reported. MVS enables view synthesis under various reflectance, transparency and lighting conditions.View full abstractDownload PDF (1438K) -
