Extensive evaluations and comparison with previous methods show that the new learning-based approach for recovering the 3D geometry of human head from a single portrait image can produce high-fidelity 3D head geometry and head pose manipulation results. D-NeRF: Neural Radiance Fields for Dynamic Scenes. Space-time Neural Irradiance Fields for Free-Viewpoint Video . Our data provide a way of quantitatively evaluating portrait view synthesis algorithms. Note that the training script has been refactored and has not been fully validated yet. arxiv:2108.04913[cs.CV]. 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. 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. We demonstrate foreshortening correction as applications[Zhao-2019-LPU, Fried-2016-PAM, Nagano-2019-DFN]. 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.

Our method produces a full reconstruction, covering not only the facial area but also the upper head, hairs, torso, and accessories such as eyeglasses. Face Deblurring using Dual Camera Fusion on Mobile Phones . Compared to the majority of deep learning face synthesis works, e.g.,[Xu-2020-D3P], which require thousands of individuals as the training data, the capability to generalize portrait view synthesis from a smaller subject pool makes our method more practical to comply with the privacy requirement on personally identifiable information. Training NeRFs for different subjects is analogous to training classifiers for various tasks. Prashanth Chandran, Derek Bradley, Markus Gross, and Thabo Beeler. Existing single-image methods use the symmetric cues[Wu-2020-ULP], morphable model[Blanz-1999-AMM, Cao-2013-FA3, Booth-2016-A3M, Li-2017-LAM], mesh template deformation[Bouaziz-2013-OMF], and regression with deep networks[Jackson-2017-LP3]. Moreover, it is feed-forward without requiring test-time optimization for each scene. Please We propose pixelNeRF, a learning framework that predicts a continuous neural scene representation conditioned on one or few input images. Dynamic Neural Radiance Fields for Monocular 4D Facial Avatar Reconstruction. Inspired by the remarkable progress of neural radiance fields (NeRFs) in photo-realistic novel view synthesis of static scenes, extensions have been proposed for . VictoriaFernandez Abrevaya, Adnane Boukhayma, Stefanie Wuhrer, and Edmond Boyer. Neural Volumes: Learning Dynamic Renderable Volumes from Images. While these models can be trained on large collections of unposed images, their lack of explicit 3D knowledge makes it difficult to achieve even basic control over 3D viewpoint without unintentionally altering identity. Our experiments show favorable quantitative results against the state-of-the-art 3D face reconstruction and synthesis algorithms on the dataset of controlled captures. Portrait Neural Radiance Fields from a Single Image Chen Gao, Yichang Shih, Wei-Sheng Lai, Chia-Kai Liang, and Jia-Bin Huang [Paper (PDF)] [Project page] (Coming soon) arXiv 2020 . 2017. To validate the face geometry learned in the finetuned model, we render the (g) disparity map for the front view (a). Using 3D morphable model, they apply facial expression tracking. We use pytorch 1.7.0 with CUDA 10.1. The high diversities among the real-world subjects in identities, facial expressions, and face geometries are challenging for training. We loop through K subjects in the dataset, indexed by m={0,,K1}, and denote the model parameter pretrained on the subject m as p,m. We render the support Ds and query Dq by setting the camera field-of-view to 84, a popular setting on commercial phone cameras, and sets the distance to 30cm to mimic selfies and headshot portraits taken on phone cameras. Bringing AI into the picture speeds things up. Recent research work has developed powerful generative models (e.g., StyleGAN2) that can synthesize complete human head images with impressive photorealism, enabling applications such as photorealistically editing real photographs. In Proc. 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. From there, a NeRF essentially fills in the blanks, training a small neural network to reconstruct the scene by predicting the color of light radiating in any direction, from any point in 3D space. Users can use off-the-shelf subject segmentation[Wadhwa-2018-SDW] to separate the foreground, inpaint the background[Liu-2018-IIF], and composite the synthesized views to address the limitation. 2020.

This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. 2020] Compared to the vanilla NeRF using random initialization[Mildenhall-2020-NRS], our pretraining method is highly beneficial when very few (1 or 2) inputs are available. In this work, we propose to pretrain the weights of a multilayer perceptron (MLP . selfie perspective distortion (foreshortening) correction[Zhao-2019-LPU, Fried-2016-PAM, Nagano-2019-DFN], improving face recognition accuracy by view normalization[Zhu-2015-HFP], and greatly enhancing the 3D viewing experiences. [width=1]fig/method/overview_v3.pdf Despite the rapid development of Neural Radiance Field (NeRF), the necessity of dense covers largely prohibits its wider applications. GIRAFFE: Representing Scenes as Compositional Generative Neural Feature Fields. Ablation study on face canonical coordinates. It is demonstrated that real-time rendering is possible by utilizing thousands of tiny MLPs instead of one single large MLP, and using teacher-student distillation for training, this speed-up can be achieved without sacrificing visual quality. SinNeRF: Training Neural Radiance Fields on Complex Scenes from a Single Image . We validate the design choices via ablation study and show that our method enables natural portrait view synthesis compared with state of the arts. A tag already exists with the provided branch name. A learning-based method for synthesizing novel views of complex scenes using only unstructured collections of in-the-wild photographs, and applies it to internet photo collections of famous landmarks, to demonstrate temporally consistent novel view renderings that are significantly closer to photorealism than the prior state of the art. The update is iterated Nq times as described in the following: where 0m=m learned from Ds in(1), 0p,m=p,m1 from the pretrained model on the previous subject, and is the learning rate for the pretraining on Dq. IEEE Trans. 2021. The first deep learning based approach to remove perspective distortion artifacts from unconstrained portraits is presented, significantly improving the accuracy of both face recognition and 3D reconstruction and enables a novel camera calibration technique from a single portrait. While NeRF has demonstrated high-quality view Since our training views are taken from a single camera distance, the vanilla NeRF rendering[Mildenhall-2020-NRS] requires inference on the world coordinates outside the training coordinates and leads to the artifacts when the camera is too far or too close, as shown in the supplemental materials. In Proc. Each subject is lit uniformly under controlled lighting conditions. 2021. i3DMM: Deep Implicit 3D Morphable Model of Human Heads. Our A-NeRF test-time optimization for monocular 3D human pose estimation jointly learns a volumetric body model of the user that can be animated and works with diverse body shapes (left). 2021b. We present a method for estimating Neural Radiance Fields (NeRF) from a single headshot portrait. Urban Radiance Fieldsallows for accurate 3D reconstruction of urban settings using panoramas and lidar information by compensating for photometric effects and supervising model training with lidar-based depth. Under the single image setting, SinNeRF significantly outperforms the . The latter includes an encoder coupled with -GAN generator to form an auto-encoder. 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. The method is based on an autoencoder that factors each input image into depth. To improve the, 2021 IEEE/CVF International Conference on Computer Vision (ICCV). NeRF[Mildenhall-2020-NRS] represents the scene as a mapping F from the world coordinate and viewing direction to the color and occupancy using a compact MLP. NeRF or better known as Neural Radiance Fields is a state . Our method can incorporate multi-view inputs associated with known camera poses to improve the view synthesis quality. For everything else, email us at [emailprotected]. 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. (or is it just me), Smithsonian Privacy Perspective manipulation. To pretrain the MLP, we use densely sampled portrait images in a light stage capture. Therefore, we provide a script performing hybrid optimization: predict a latent code using our model, then perform latent optimization as introduced in pi-GAN. When the camera sets a longer focal length, the nose looks smaller, and the portrait looks more natural. In Proc. GANSpace: Discovering Interpretable GAN Controls.

This website is inspired by the template of Michal Gharbi. Instead of training the warping effect between a set of pre-defined focal lengths[Zhao-2019-LPU, Nagano-2019-DFN], our method achieves the perspective effect at arbitrary camera distances and focal lengths. 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 ECCV. 3D Morphable Face Models - Past, Present and Future. NVIDIA websites use cookies to deliver and improve the website experience. 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. This work describes how to effectively optimize neural radiance fields to render photorealistic novel views of scenes with complicated geometry and appearance, and demonstrates results that outperform prior work on neural rendering and view synthesis.

We take a step towards resolving these shortcomings Our method takes a lot more steps in a single meta-training task for better convergence. Proc. 94219431. (a) When the background is not removed, our method cannot distinguish the background from the foreground and leads to severe artifacts. This is a challenging task, as training NeRF requires multiple views of the same scene, coupled with corresponding poses, which are hard to obtain. [Xu-2020-D3P] generates plausible results but fails to preserve the gaze direction, facial expressions, face shape, and the hairstyles (the bottom row) when comparing to the ground truth. We propose a method to learn 3D deformable object categories from raw single-view images, without external supervision. On the other hand, recent Neural Radiance Field (NeRF) methods have already achieved multiview-consistent, photorealistic renderings but they are so far limited to a single facial identity. NeRF fits multi-layer perceptrons (MLPs) representing view-invariant opacity and view-dependent color volumes to a set of training images, and samples novel views based on volume . Peng Zhou, Lingxi Xie, Bingbing Ni, and Qi Tian. 2021. To achieve high-quality view synthesis, the filmmaking production industry densely samples lighting conditions and camera poses synchronously around a subject using a light stage[Debevec-2000-ATR]. 2021.

[1/4]" The existing approach for constructing neural radiance fields [27] involves optimizing the representation to every scene independently, requiring many calibrated views and significant compute time. 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. 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. Since Dq is unseen during the test time, we feedback the gradients to the pretrained parameter p,m to improve generalization. DynamicFusion: Reconstruction and tracking of non-rigid scenes in real-time. ECCV. In Proc. Cited by: 2. Specifically, for each subject m in the training data, we compute an approximate facial geometry Fm from the frontal image using a 3D morphable model and image-based landmark fitting[Cao-2013-FA3]. 2020. ICCV Workshops. In total, our dataset consists of 230 captures. The center view corresponds to the front view expected at the test time, referred to as the support set Ds, and the remaining views are the target for view synthesis, referred to as the query set Dq. 343352. In International Conference on 3D Vision (3DV). While NeRF has demonstrated high-quality view synthesis,. Pretraining with meta-learning framework. Tero Karras, Samuli Laine, and Timo Aila. Our method takes the benefits from both face-specific modeling and view synthesis on generic scenes. By virtually moving the camera closer or further from the subject and adjusting the focal length correspondingly to preserve the face area, we demonstrate perspective effect manipulation using portrait NeRF inFigure8 and the supplemental video. While NeRF has demonstrated high-quality view synthesis, it requires multiple images of static scenes and thus impractical for casual captures and moving subjects. Our method builds upon the recent advances of neural implicit representation and addresses the limitation of generalizing to an unseen subject when only one single image is available. Our method outputs a more natural look on face inFigure10(c), and performs better on quality metrics against ground truth across the testing subjects, as shown inTable3.
