While simply satisfying the radiance field over the input image does not guarantee a correct geometry, . Jia-Bin Huang Virginia Tech Abstract We present a method for estimating Neural Radiance Fields (NeRF) from a single headshot portrait. 2021. Local image features were used in the related regime of implicit surfaces in, Our MLP architecture is Active Appearance Models. 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. We refer to the process training a NeRF model parameter for subject m from the support set as a task, denoted by Tm. If nothing happens, download GitHub Desktop and try again. PAMI PP (Oct. 2020). In addition, we show thenovel application of a perceptual loss on the image space is critical forachieving photorealism. While NeRF has demonstrated high-quality view synthesis, it requires multiple images of static scenes and thus impractical for casual captures and moving subjects. We stress-test the challenging cases like the glasses (the top two rows) and curly hairs (the third row). While NeRF has demonstrated high-quality view Anurag Ranjan, Timo Bolkart, Soubhik Sanyal, and MichaelJ. It may not reproduce exactly the results from the paper. 2020. 8649-8658. 2020. We further demonstrate the flexibility of pixelNeRF by demonstrating it on multi-object ShapeNet scenes and real scenes from the DTU dataset. Our results faithfully preserve the details like skin textures, personal identity, and facial expressions from the input. 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. Portrait Neural Radiance Fields from a Single Image. 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. arXiv as responsive web pages so you Emilien Dupont and Vincent Sitzmann for helpful discussions. We first compute the rigid transform described inSection3.3 to map between the world and canonical coordinate. 40, 6, Article 238 (dec 2021).

We quantitatively evaluate the method using controlled captures and demonstrate the generalization to real portrait images, showing favorable results against state-of-the-arts. CVPR. In this paper, we propose to train an MLP for modeling the radiance field using a single headshot portrait illustrated in Figure1. To manage your alert preferences, click on the button below. Unconstrained Scene Generation with Locally Conditioned Radiance Fields. Please send any questions or comments to Alex Yu. In contrast, our method requires only one single image as input. Our method can also seemlessly integrate multiple views at test-time to obtain better results. We train MoRF in a supervised fashion by leveraging a high-quality database of multiview portrait images of several people, captured in studio with polarization-based separation of diffuse and specular reflection. This includes training on a low-resolution rendering of aneural radiance field, together with a 3D-consistent super-resolution moduleand mesh-guided space canonicalization and sampling. Graph. Without any pretrained prior, the random initialization[Mildenhall-2020-NRS] inFigure9(a) fails to learn the geometry from a single image and leads to poor view synthesis quality. The method is based on an autoencoder that factors each input image into depth. Instant NeRF, however, cuts rendering time by several orders of magnitude. In Proc. NeRF: Representing Scenes as Neural Radiance Fields for View Synthesis. Ablation study on initialization methods. 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. , denoted as LDs(fm). 86498658. 2021. Extensive experiments are conducted on complex scene benchmarks, including NeRF synthetic dataset, Local Light Field Fusion dataset, and DTU dataset. to use Codespaces. Volker Blanz and Thomas Vetter. We propose a method to learn 3D deformable object categories from raw single-view images, without external supervision. The warp makes our method robust to the variation in face geometry and pose in the training and testing inputs, as shown inTable3 andFigure10. They reconstruct 4D facial avatar neural radiance field from a short monocular portrait video sequence to synthesize novel head poses and changes in facial expression. While NeRF has demonstrated high-quality view synthesis, it requires multiple images of static scenes and thus impractical for casual captures and moving subjects. We present a method for estimating Neural Radiance Fields (NeRF) from a single headshot portrait. (a) When the background is not removed, our method cannot distinguish the background from the foreground and leads to severe artifacts. We finetune the pretrained weights learned from light stage training data[Debevec-2000-ATR, Meka-2020-DRT] for unseen inputs. The learning-based head reconstruction method from Xuet al.

Figure3 and supplemental materials show examples of 3-by-3 training views. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. In Proc. Using a new input encoding method, researchers can achieve high-quality results using a tiny neural network that runs rapidly. We propose an algorithm to pretrain NeRF in a canonical face space using a rigid transform from the world coordinate. Moreover, it is feed-forward without requiring test-time optimization for each scene.

View synthesis with neural implicit representations. NeurIPS. A tag already exists with the provided branch name. Input views in test time. Our approach operates in view-spaceas opposed to canonicaland requires no test-time optimization. We propose pixelNeRF, a learning framework that predicts a continuous neural scene representation conditioned on one or few input images. We show that even whouzt pre-training on multi-view datasets, SinNeRF can yield photo-realistic novel-view synthesis results. To render novel views, we sample the camera ray in the 3D space, warp to the canonical space, and feed to fs to retrieve the radiance and occlusion for volume rendering. There was a problem preparing your codespace, please try again. As illustrated in Figure12(a), our method cannot handle the subject background, which is diverse and difficult to collect on the light stage. There was a problem preparing your codespace, please try again. Our pretraining inFigure9(c) outputs the best results against the ground truth. IEEE Trans.

Reconstructing face geometry and texture enables view synthesis using graphics rendering pipelines. D-NeRF: Neural Radiance Fields for Dynamic Scenes. Specifically, SinNeRF constructs a semi-supervised learning process, where we introduce and propagate geometry pseudo labels and semantic pseudo labels to guide the progressive training process. Given a camera pose, one can synthesize the corresponding view by aggregating the radiance over the light ray cast from the camera pose using standard volume rendering. Towards a complete 3D morphable model of the human head. Chen Gao, Yi-Chang Shih, Wei-Sheng Lai, Chia-Kai Liang, Jia-Bin Huang: Portrait Neural Radiance Fields from a Single Image. We also thank Jrmy Riviere, Paulo Gotardo, Derek Bradley, Abhijeet Ghosh, and Thabo Beeler. Eric Chan, Marco Monteiro, Petr Kellnhofer, Jiajun Wu, and Gordon Wetzstein. Our results improve when more views are available. This work introduces three objectives: a batch distribution loss that encourages the output distribution to match the distribution of the morphable model, a loopback loss that ensures the network can correctly reinterpret its own output, and a multi-view identity loss that compares the features of the predicted 3D face and the input photograph from multiple viewing angles. These excluded regions, however, are critical for natural portrait view synthesis. In this work, we make the following contributions: We present a single-image view synthesis algorithm for portrait photos by leveraging meta-learning. such as pose manipulation[Criminisi-2003-GMF], In our experiments, the pose estimation is challenging at the complex structures and view-dependent properties, like hairs and subtle movement of the subjects between captures. Our results look realistic, preserve the facial expressions, geometry, identity from the input, handle well on the occluded area, and successfully synthesize the clothes and hairs for the subject. TimothyF. Cootes, GarethJ. Edwards, and ChristopherJ. Taylor. Abstract: We propose a pipeline to generate Neural Radiance Fields (NeRF) of an object or a scene of a specific class, conditioned on a single input image. we apply a model trained on ShapeNet planes, cars, and chairs to unseen ShapeNet categories. Without warping to the canonical face coordinate, the results using the world coordinate inFigure10(b) show artifacts on the eyes and chins. ACM Trans. Work fast with our official CLI. 2021. Unlike previous few-shot NeRF approaches, our pipeline is unsupervised, capable of being trained with independent images without 3D, multi-view, or pose supervision. Katja Schwarz, Yiyi Liao, Michael Niemeyer, and Andreas Geiger. To attain this goal, we present a Single View NeRF (SinNeRF) framework consisting of thoughtfully designed semantic and geometry regularizations. We propose pixelNeRF, a learning framework that predicts a continuous neural scene representation conditioned on We sequentially train on subjects in the dataset and update the pretrained model as {p,0,p,1,p,K1}, where the last parameter is outputted as the final pretrained model,i.e., p=p,K1. Perspective manipulation. 36, 6 (nov 2017), 17pages. 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. We also address the shape variations among subjects by learning the NeRF model in canonical face space. 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. Curran Associates, Inc., 98419850. To improve the generalization to unseen faces, we train the MLP in the canonical coordinate space approximated by 3D face morphable models. We thank Shubham Goel and Hang Gao for comments on the text. 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. 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]. CVPR. Neural Volumes: Learning Dynamic Renderable Volumes from Images. Edgar Tretschk, Ayush Tewari, Vladislav Golyanik, Michael Zollhfer, Christoph Lassner, and Christian Theobalt. 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. We assume that the order of applying the gradients learned from Dq and Ds are interchangeable, similarly to the first-order approximation in MAML algorithm[Finn-2017-MAM]. A style-based generator architecture for generative adversarial networks. Portraits taken by wide-angle cameras exhibit undesired foreshortening distortion due to the perspective projection [Fried-2016-PAM, Zhao-2019-LPU]. Feed-forward NeRF from One View. Use Git or checkout with SVN using the web URL. Showcased in a session at NVIDIA GTC this week, Instant NeRF could be used to create avatars or scenes for virtual worlds, to capture video conference participants and their environments in 3D, or to reconstruct scenes for 3D digital maps. We present a method for estimating Neural Radiance Fields (NeRF) from a single headshot portrait. We train a model m optimized for the front view of subject m using the L2 loss between the front view predicted by fm and Ds Addressing the finetuning speed and leveraging the stereo cues in dual camera popular on modern phones can be beneficial to this goal. Portrait view synthesis enables various post-capture edits and computer vision applications, arXiv preprint arXiv:2012.05903. IEEE, 81108119. In the pretraining stage, we train a coordinate-based MLP (same in NeRF) f on diverse subjects captured from the light stage and obtain the pretrained model parameter optimized for generalization, denoted as p(Section3.2).

Leveraging the volume rendering approach of NeRF, our model can be trained directly from images with no explicit 3D supervision. Inspired by the remarkable progress of neural radiance fields (NeRFs) in photo-realistic novel view synthesis of static scenes, extensions have been proposed for . To improve the generalization to unseen faces, we train the MLP in the canonical coordinate space approximated by 3D face morphable models. GANSpace: Discovering Interpretable GAN Controls. Our method can incorporate multi-view inputs associated with known camera poses to improve the view synthesis quality. Under the single image setting, SinNeRF significantly outperforms the current state-of-the-art NeRF baselines in all cases. Rigid transform between the world and canonical face coordinate. Discussion. We provide pretrained model checkpoint files for the three datasets. This alert has been successfully added and will be sent to: You will be notified whenever a record that you have chosen has been cited. Our key idea is to pretrain the MLP and finetune it using the available input image to adapt the model to an unseen subjects appearance and shape. CVPR. We show that compensating the shape variations among the training data substantially improves the model generalization to unseen subjects. In Proc. Ablation study on different weight initialization. Reconstructing the facial geometry from a single capture requires face mesh templates[Bouaziz-2013-OMF] or a 3D morphable model[Blanz-1999-AMM, Cao-2013-FA3, Booth-2016-A3M, Li-2017-LAM]. Non-Rigid Neural Radiance Fields: Reconstruction and Novel View Synthesis of a Dynamic Scene From Monocular Video. Compared to the unstructured light field [Mildenhall-2019-LLF, Flynn-2019-DVS, Riegler-2020-FVS, Penner-2017-S3R], volumetric rendering[Lombardi-2019-NVL], and image-based rendering[Hedman-2018-DBF, Hedman-2018-I3P], our single-image method does not require estimating camera pose[Schonberger-2016-SFM]. In our method, the 3D model is used to obtain the rigid transform (sm,Rm,tm). A tag already exists with the provided branch name. We demonstrate foreshortening correction as applications[Zhao-2019-LPU, Fried-2016-PAM, Nagano-2019-DFN]. 2021. 2020. ECCV. While the outputs are photorealistic, these approaches have common artifacts that the generated images often exhibit inconsistent facial features, identity, hairs, and geometries across the results and the input image. SIGGRAPH) 38, 4, Article 65 (July 2019), 14pages. Abstract: Reasoning the 3D structure of a non-rigid dynamic scene from a single moving camera is an under-constrained problem. 2020.

The command to use is: python --path PRETRAINED_MODEL_PATH --output_dir OUTPUT_DIRECTORY --curriculum ["celeba" or "carla" or "srnchairs"] --img_path /PATH_TO_IMAGE_TO_OPTIMIZE/ We address the variation by normalizing the world coordinate to the canonical face coordinate using a rigid transform and train a shape-invariant model representation (Section3.3). The margin decreases when the number of input views increases and is less significant when 5+ input views are available. The results from [Xu-2020-D3P] were kindly provided by the authors. CVPR. 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. HoloGAN is the first generative model that learns 3D representations from natural images in an entirely unsupervised manner and is shown to be able to generate images with similar or higher visual quality than other generative models. It is thus impractical for portrait view synthesis because Our training data consists of light stage captures over multiple subjects. Recent research indicates that we can make this a lot faster by eliminating deep learning. By clicking accept or continuing to use the site, you agree to the terms outlined in our.

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. We average all the facial geometries in the dataset to obtain the mean geometry F. The transform is used to map a point x in the subjects world coordinate to x in the face canonical space: x=smRmx+tm, where sm,Rm and tm are the optimized scale, rotation, and translation. In all cases, pixelNeRF outperforms current state-of-the-art baselines for novel view synthesis and single image 3D reconstruction. IEEE, 44324441. Figure5 shows our results on the diverse subjects taken in the wild. This is a challenging task, as training NeRF requires multiple views of the same scene, coupled with corresponding poses, which are hard to obtain.

First, we leverage gradient-based meta-learning techniques[Finn-2017-MAM] to train the MLP in a way so that it can quickly adapt to an unseen subject. 2019. 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. While several recent works have attempted to address this issue, they either operate with sparse views (yet still, a few of them) or on simple objects/scenes. Pretraining on Ds. (c) Finetune. CVPR. The neural network for parametric mapping is elaborately designed to maximize the solution space to represent diverse identities and expressions. We take a step towards resolving these shortcomings Figure2 illustrates the overview of our method, which consists of the pretraining and testing stages. While NeRF has demonstrated high-quality view synthesis, it requires multiple images of static scenes and thus impractical for casual captures and moving subjects. ICCV Workshops.
