Creating high-fidelity 3D head avatars has always been a research hotspot but there
remains a great challenge under lightweight sparse view setups. In this paper we propose …

The fidelity of relighting is bounded by both geometry and appearance representations. For
geometry both mesh and volumetric approaches have difficulty modeling intricate structures …

Unlike previous studies on the Metaverse based on Second Life, the current Metaverse is
based on the social value of Generation Z that online and offline selves are not different …

This paper presents a novel neural implicit radiance representation for free viewpoint
relighting from a small set of unstructured photographs of an object lit by a moving point light …

Single-image relighting is a challenging task that involves reasoning about the complex
interplay between geometry, materials, and lighting. Many prior methods either support only …
