The FoV-NeRF Paper from DALAB of SEIEE Won Best IEEE ISMAR 2022 Journal Paper Award

The 21th International Symposium on Mixed and Augmented Reality (ISMAR 2022) has recently been successfully completed in Singapore. The paper “FoV-NeRF: Foveated Neural Radiance Fields for Virtual Reality” contributed by Prof. Xubo Yang’s team from Digital ART Laboratory, School of Software Engineering, SEIEE, won the Best IEEE ISMAR 2022 Journal Paper Award. The paper is published in IEEE TVCG (CCF Recommended Class A Journal), the top journal in the field of visualization and computer graphics. The first three authors of the paper are Nianchen Deng (Ph.D. candidate of SJTU), Zhenyi He (M.S. of SJTU, Ph.D. of New York University), and Jiannan Ye (Ph.D. candidate of SJTU), with Prof. Xubo Yang as the joint corresponding author.


Contributions of the FoV-NeRF Paper

An essential need for future VR/AR is to teleport different users and environments for collaborative scenarios, requiring high-quality and low latency for real-time rendering. The neural radiance fields (NeRF) demonstrated that photo-realistic quality and continuous view changes of 3D scenes could be achieved without loss of view-dependent effects. While NeRF can significantly benefit rendering for VR applications, it faces unique challenges posed by high field-of-view, high resolution, and stereoscopic/egocentric viewing of VR, typically causing low quality and high latency of the rendered images.

FoV-NeRF presents the first gaze-contingent 3D neural representation and view synthesis method. It incorporates the human psychophysics of visual- and stereo-acuity into an egocentric neural representation of 3D scenery. It then jointly optimizes the latency/performance and visual quality while mutually bridging human perception and neural scene synthesis to achieve perceptually high-quality immersive interaction. The results showed that the proposed method significantly reduces latency (up to 99% time reduction compared with NeRF) without loss of high-fidelity rendering (perceptually identical to full-resolution ground truth). The presented approach may serve as the first step toward future VR/AR systems that capture, teleport, and visualize remote environments in real time.
