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]. 33. Edgar Tretschk, Ayush Tewari, Vladislav Golyanik, Michael Zollhfer, Christoph Lassner, and Christian Theobalt. To leverage the domain-specific knowledge about faces, we train on a portrait dataset and propose the canonical face coordinates using the 3D face proxy derived by a morphable model. 2020. 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. Using 3D morphable model, they apply facial expression tracking. Since its a lightweight neural network, it can be trained and run on a single NVIDIA GPU running fastest on cards with NVIDIA Tensor Cores. 40, 6 (dec 2021). To improve the generalization to unseen faces, we train the MLP in the canonical coordinate space approximated by 3D face morphable models. We present a method for estimating Neural Radiance Fields (NeRF) from a single headshot portrait. Our method generalizes well due to the finetuning and canonical face coordinate, closing the gap between the unseen subjects and the pretrained model weights learned from the light stage dataset. Peng Zhou, Lingxi Xie, Bingbing Ni, and Qi Tian. At the test time, given a single label from the frontal capture, our goal is to optimize the testing task, which learns the NeRF to answer the queries of camera poses. Our method takes the benefits from both face-specific modeling and view synthesis on generic scenes. Tero Karras, Samuli Laine, Miika Aittala, Janne Hellsten, Jaakko Lehtinen, and Timo Aila. RichardA Newcombe, Dieter Fox, and StevenM Seitz. Our approach operates in view-spaceas opposed to canonicaland requires no test-time optimization. The synthesized face looks blurry and misses facial details. The latter includes an encoder coupled with -GAN generator to form an auto-encoder. PAMI PP (Oct. 2020). 1999. In this work, we consider a more ambitious task: training neural radiance field, over realistically complex visual scenes, by looking only once, i.e., using only a single view. VictoriaFernandez Abrevaya, Adnane Boukhayma, Stefanie Wuhrer, and Edmond Boyer. We present a method for estimating Neural Radiance Fields (NeRF) from a single headshot portrait. 2020.

However, using a nave pretraining process that optimizes the reconstruction error between the synthesized views (using the MLP) and the rendering (using the light stage data) over the subjects in the dataset performs poorly for unseen subjects due to the diverse appearance and shape variations among humans. 2019. To attain this goal, we present a Single View NeRF (SinNeRF) framework consisting of thoughtfully designed semantic and geometry regularizations. Our method does not require a large number of training tasks consisting of many subjects. We use pytorch 1.7.0 with CUDA 10.1. Graphics (Proc. Non-Rigid Neural Radiance Fields: Reconstruction and Novel View Synthesis of a Dynamic Scene From Monocular Video.

The NVIDIA Research team has developed an approach that accomplishes this task almost instantly making it one of the first models of its kind to combine ultra-fast neural network training and rapid rendering. Chia-Kai Liang, Jia-Bin Huang: Portrait Neural Radiance Fields from a Single . At the test time, we initialize the NeRF with the pretrained model parameter p and then finetune it on the frontal view for the input subject s. We finetune the pretrained weights learned from light stage training data[Debevec-2000-ATR, Meka-2020-DRT] for unseen inputs. 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. Bundle-Adjusting Neural Radiance Fields (BARF) is proposed for training NeRF from imperfect (or even unknown) camera poses the joint problem of learning neural 3D representations and registering camera frames and it is shown that coarse-to-fine registration is also applicable to NeRF.

Albert Pumarola, Enric Corona, Gerard Pons-Moll, and Francesc Moreno-Noguer. Discussion. Our method requires the input subject to be roughly in frontal view and does not work well with the profile view, as shown inFigure12(b). Our pretraining inFigure9(c) outputs the best results against the ground truth. While simply satisfying the radiance field over the input image does not guarantee a correct geometry, . As illustrated in Figure12(a), our method cannot handle the subject background, which is diverse and difficult to collect on the light stage. CVPR. GIRAFFE: Representing Scenes as Compositional Generative Neural Feature Fields. Semantic Scholar is a free, AI-powered research tool for scientific literature, based at the Allen Institute for AI.

Title:Portrait Neural Radiance Fields from a Single Image Authors:Chen Gao, Yichang Shih, Wei-Sheng Lai, Chia-Kai Liang, Jia-Bin Huang Download PDF Abstract:We present a method for estimating Neural Radiance Fields (NeRF) from a single headshot portrait. In this paper, we propose a new Morphable Radiance Field (MoRF) method that extends a NeRF into a generative neural model that can realistically synthesize multiview-consistent images of complete human heads, with variable and controllable identity. ACM Trans. We thank the authors for releasing the code and providing support throughout the development of this project. We address the challenges in two novel ways. The disentangled parameters of shape, appearance and expression can be interpolated to achieve a continuous and morphable facial synthesis. Ricardo Martin-Brualla, Noha Radwan, Mehdi S.M. Sajjadi, JonathanT. Barron, Alexey Dosovitskiy, and Daniel Duckworth. Limitations. 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. Figure10 andTable3 compare the view synthesis using the face canonical coordinate (Section3.3) to the world coordinate. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Qualitative and quantitative experiments demonstrate that the Neural Light Transport (NLT) outperforms state-of-the-art solutions for relighting and view synthesis, without requiring separate treatments for both problems that prior work requires. Training NeRFs for different subjects is analogous to training classifiers for various tasks. Similarly to the neural volume method[Lombardi-2019-NVL], our method improves the rendering quality by sampling the warped coordinate from the world coordinates. 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. SIGGRAPH '22: ACM SIGGRAPH 2022 Conference Proceedings. Unlike NeRF[Mildenhall-2020-NRS], training the MLP with a single image from scratch is fundamentally ill-posed, because there are infinite solutions where the renderings match the input image. Recent research indicates that we can make this a lot faster by eliminating deep learning. While NeRF has demonstrated high-quality view synthesis, it requires multiple images of static scenes and thus impractical for casual captures and moving subjects. CVPR. While estimating the depth and appearance of an object based on a partial view is a natural skill for humans, its a demanding task for AI. Download from https://www.dropbox.com/s/lcko0wl8rs4k5qq/pretrained_models.zip?dl=0 and unzip to use. Since Dq is unseen during the test time, we feedback the gradients to the pretrained parameter p,m to improve generalization. For example, Neural Radiance Fields (NeRF) demonstrates high-quality view synthesis by implicitly modeling the volumetric density and color using the weights of a multilayer perceptron (MLP). We first compute the rigid transform described inSection3.3 to map between the world and canonical coordinate. Semantic Deep Face Models.

ICCV. Since Ds is available at the test time, we only need to propagate the gradients learned from Dq to the pretrained model p, which transfers the common representations unseen from the front view Ds alone, such as the priors on head geometry and occlusion. We propose FDNeRF, the first neural radiance field to reconstruct 3D faces from few-shot dynamic frames. DietNeRF improves the perceptual quality of few-shot view synthesis when learned from scratch, can render novel views with as few as one observed image when pre-trained on a multi-view dataset, and produces plausible completions of completely unobserved regions.

If traditional 3D representations like polygonal meshes are akin to vector images, NeRFs are like bitmap images: they densely capture the way light radiates from an object or within a scene, says David Luebke, vice president for graphics research at NVIDIA. When the first instant photo was taken 75 years ago with a Polaroid camera, it was groundbreaking to rapidly capture the 3D world in a realistic 2D image. To address the face shape variations in the training dataset and real-world inputs, we normalize the world coordinate to the canonical space using a rigid transform and apply f on the warped coordinate.
