ICCV. We present a method for estimating Neural Radiance Fields (NeRF) from a single headshot portrait. Collecting data to feed a NeRF is a bit like being a red carpet photographer trying to capture a celebritys outfit from every angle the neural network requires a few dozen images taken from multiple positions around the scene, as well as the camera position of each of those shots. arXiv preprint arXiv:2110.09788(2021). Experimental results demonstrate that the novel framework can produce high-fidelity and natural results, and support free adjustment of audio signals, viewing directions, and background images. Keunhong Park, Utkarsh Sinha, Peter Hedman, JonathanT. Barron, Sofien Bouaziz, DanB Goldman, Ricardo Martin-Brualla, and StevenM. Seitz. To explain the analogy, we consider view synthesis from a camera pose as a query, captures associated with the known camera poses from the light stage dataset as labels, and training a subject-specific NeRF as a task. We also thank Recent research indicates that we can make this a lot faster by eliminating deep learning. Our method preserves temporal coherence in challenging areas like hairs and occlusion, such as the nose and ears.

In addition, we show thenovel application of a perceptual loss on the image space is critical forachieving photorealism. 2020. Conditioned on the input portrait, generative methods learn a face-specific Generative Adversarial Network (GAN)[Goodfellow-2014-GAN, Karras-2019-ASB, Karras-2020-AAI] to synthesize the target face pose driven by exemplar images[Wu-2018-RLT, Qian-2019-MAF, Nirkin-2019-FSA, Thies-2016-F2F, Kim-2018-DVP, Zakharov-2019-FSA], rig-like control over face attributes via face model[Tewari-2020-SRS, Gecer-2018-SSA, Ghosh-2020-GIF, Kowalski-2020-CCN], or learned latent code [Deng-2020-DAC, Alharbi-2020-DIG]. While the quality of these 3D model-based methods has been improved dramatically via deep networks[Genova-2018-UTF, Xu-2020-D3P], a common limitation is that the model only covers the center of the face and excludes the upper head, hairs, and torso, due to their high variability. Beyond NeRFs, NVIDIA researchers are exploring how this input encoding technique might be used to accelerate multiple AI challenges including reinforcement learning, language translation and general-purpose deep learning algorithms. SIGGRAPH) 38, 4, Article 65 (July 2019), 14pages. While NeRF has demonstrated high-quality view synthesis, it requires multiple images of static scenes and thus impractical for casual captures and moving subjects. In Proc. we capture 2-10 different expressions, poses, and accessories on a light stage under fixed lighting conditions. This is because each update in view synthesis requires gradients gathered from millions of samples across the scene coordinates and viewing directions, which do not fit into a single batch in modern GPU. 2021.

Comparisons. python linear_interpolation --path=/PATH_TO/checkpoint_train.pth --output_dir=/PATH_TO_WRITE_TO/. The disentangled parameters of shape, appearance and expression can be interpolated to achieve a continuous and morphable facial synthesis. We obtain the results of Jacksonet al. Our work is a first step toward the goal that makes NeRF practical with casual captures on hand-held devices. The proposed FDNeRF accepts view-inconsistent dynamic inputs and supports arbitrary facial expression editing, i.e., producing faces with novel expressions beyond the input ones, and introduces a well-designed conditional feature warping module to perform expression conditioned warping in 2D feature space. In Proc. 2018. As a strength, we preserve the texture and geometry information of the subject across camera poses by using the 3D neural representation invariant to camera poses[Thies-2019-Deferred, Nguyen-2019-HUL] and taking advantage of pose-supervised training[Xu-2019-VIG]. We take a step towards resolving these shortcomings by . We leverage gradient-based meta-learning algorithms[Finn-2017-MAM, Sitzmann-2020-MML] to learn the weight initialization for the MLP in NeRF from the meta-training tasks, i.e., learning a single NeRF for different subjects in the light stage dataset. Ablation study on face canonical coordinates. While NeRF has demonstrated high-quality view ACM Trans. This paper introduces a method to modify the apparent relative pose and distance between camera and subject given a single portrait photo, and builds a 2D warp in the image plane to approximate the effect of a desired change in 3D.

Our method is visually similar to the ground truth, synthesizing the entire subject, including hairs and body, and faithfully preserving the texture, lighting, and expressions. In Proc. In contrast, our method requires only one single image as input. GANSpace: Discovering Interpretable GAN Controls. However, these model-based methods only reconstruct the regions where the model is defined, and therefore do not handle hairs and torsos, or require a separate explicit hair modeling as post-processing[Xu-2020-D3P, Hu-2015-SVH, Liang-2018-VTF]. Neural Volumes: Learning Dynamic Renderable Volumes from Images. PVA: Pixel-aligned Volumetric Avatars. In contrast, previous method shows inconsistent geometry when synthesizing novel views. While generating realistic images is no longer a difficult task, producing the corresponding 3D structure such that they can be rendered from different views is non-trivial. The subjects cover various ages, gender, races, and skin colors. NeRF: Representing Scenes as Neural Radiance Fields for View Synthesis. Portrait Neural Radiance Fields from a Single Image. We address the challenges in two novel ways.
