  text: Achieving photorealistic 3D view synthesis and relighting of human portraits
    is pivotal for advancing AR/VR applications. Existing methodologies in portrait
    relighting demonstrate substantial limitations in terms of generalization and
    3D consistency, coupled with inaccuracies in physically realistic lighting and
    identity preservation. Furthermore, personalization from a single view is difficult
    to achieve and often requires multiview images during the testing phase or involves
    slow optimization processes. This paper introduces Lite2Relight , a novel technique
    that can predict 3D consistent head poses of portraits while performing physically
    plausible light editing at interactive speed. Our method uniquely extends the
    generative capabilities and efficient volumetric representation of EG3D, leveraging
    a lightstage dataset to implicitly disentangle face reflectance and perform relighting
    under target HDRI environment maps. By utilizing a pre-trained geometry-aware
    encoder and a feature alignment module, we map input images into a relightable
    3D space, enhancing them with a strong face geometry and reflectance prior. Through
    extensive quantitative and qualitative evaluations, we show that our method outperforms
    the state-of-the-art methods in terms of efficacy, photorealism, and practical
    application. This includes producing 3D-consistent results of the full head, including
    hair, eyes, and expressions. Lite2Relight paves the way for large-scale adoption
    of photorealistic portrait editing in various domains, offering a robust, interactive
    solution to a previously constrained problem.
