However, the enormous size of light field limits their utilization for streaming and 3D display applications. In this paper, we propose a novel representation, coding and streaming scheme for dynamic light fields based on a novel Hybrid Tucker TensorSketch Vector Quantization (HTTSVQ) algorithm. A dynamic light field can be generated from a static light field to capture a moving 3D scene. We acquire images through different coded aperture patterns for a dynamic light field and perform their low-rank approximation using our HTTSVQ scheme, followed by encoding with High Efficiency Video Coding (HEVC). The proposed single pass coding scheme can incrementally handle tensor elements and thus enables to stream and compress light field data without the need to store it in full. Additional encoding of low-rank approximated acquired images by HEVC eliminates intra-frame, inter-frame and intrinsic redundancies in light field data. Comparison with state-of-the-art coders HEVC and its multi-view extension (MV-HEVC) exhibits superior compression performance of the proposed scheme for real-world light fields.","PeriodicalId":382937,"journal":{"name":"2021 International Conference on 3D Immersion (IC3D)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133077610","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These contexts of light field display utilization fundamentally depend on the distance of observation, due to the sheer technological nature of such glasses-free 3D systems. Yet, at the time of this paper, the number of works in the scientific literature that address viewing distance is rather limited, focusing solely on 3D visual experience based on angular density. Thus far, the personal preference of observers regarding viewing distance has not been considered by studies. Furthermore, the upcoming standardization efforts also necessitate research on the topic in order to coherently unify the methodologies of subjective tests. In this paper, we investigate the perceptually-supported and the subjectively-preferred viewing distance of light field visualization. We carried out a series of tests on multiple projection-based light field displays to study these distances, with the separate involvement of experts and regular test participants.","PeriodicalId":382937,"journal":{"name":"2021 International Conference on 3D Immersion (IC3D)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131164471","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As such, static light fields have application opportunities in heterogeneous domains, including education, cultural heritage and entertainment. This paper contributes the design, implementation and performance evaluation of a web-based static light field consumption system. The proposed system allows static light field datasets to be adaptively streamed over the network and then to be visualized in a vanilla web browser. The performance evaluation results prove that real-time consumption of static light fields at AR/VR-compatible framerates of 90 FPS or more is feasible on commercial off-the-shelf hardware. Given the ubiquitous availability of web browsers on modern consumption devices (PCs, smart TVs, Head Mounted Displays, . . . ), our work is intended to significantly improve the accessibility and exploitation of static light field technology. The JavaScript client code is open-sourced to maximize our work’s impact.","PeriodicalId":382937,"journal":{"name":"2021 International Conference on 3D Immersion (IC3D)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130648272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
