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. RT @cwolferesearch: One of the main limitations of Neural Radiance Fields (NeRFs) is that training them requires many images and a lot of time (several days on a single GPU). 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. Ablation study on initialization methods. To improve the generalization to unseen faces, we train the MLP in the canonical coordinate space approximated by 3D face morphable models. It is thus impractical for portrait view synthesis because In addition, we show thenovel application of a perceptual loss on the image space is critical forachieving photorealism. A morphable model for the synthesis of 3D faces. We finetune the pretrained weights learned from light stage training data[Debevec-2000-ATR, Meka-2020-DRT] for unseen inputs.

Ziyan Wang, Timur Bagautdinov, Stephen Lombardi, Tomas Simon, Jason Saragih, Jessica Hodgins, and Michael Zollhfer. 41414148. In all cases, pixelNeRF outperforms current state-of-the-art baselines for novel view synthesis and single image 3D reconstruction. CVPR. 2020. While NeRF has demonstrated high-quality view synthesis, it requires multiple images of static scenes and thus impractical for casual captures and moving subjects. 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. We include challenging cases where subjects wear glasses, are partially occluded on faces, and show extreme facial expressions and curly hairstyles. In Proc. 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. inspired by, Parts of our Wenqi Xian, Jia-Bin Huang, Johannes Kopf, and Changil Kim. 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). Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Despite the rapid development of Neural Radiance Field (NeRF), the necessity of dense covers largely prohibits its wider applications. to use Codespaces. You signed in with another tab or window.

If you find a rendering bug, file an issue on GitHub. 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. In a scene that includes people or other moving elements, the quicker these shots are captured, the better. ShahRukh Athar, Zhixin Shu, and Dimitris Samaras. In this paper, we propose to train an MLP for modeling the radiance field using a single headshot portrait illustrated in Figure1. D-NeRF: Neural Radiance Fields for Dynamic Scenes. DynamicFusion: Reconstruction and tracking of non-rigid scenes in real-time. CVPR. Similarly to the neural volume method[Lombardi-2019-NVL], our method improves the rendering quality by sampling the warped coordinate from the world coordinates. In contrast, our method requires only one single image as input. 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.

Bringing AI into the picture speeds things up. 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). 2021. 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. The result, dubbed Instant NeRF, is the fastest NeRF technique to date, achieving more than 1,000x speedups in some cases. (b) Warp to canonical coordinate While NeRF has demonstrated high-quality view synthesis, it requires multiple images of static scenes and thus impractical for casual captures and moving subjects. 1999. We do not require the mesh details and priors as in other model-based face view synthesis[Xu-2020-D3P, Cao-2013-FA3]. To pretrain the MLP, we use densely sampled portrait images in a light stage capture. Neural volume renderingrefers to methods that generate images or video by tracing a ray into the scene and taking an integral of some sort over the length of the ray. ACM Trans.

The disentangled parameters of shape, appearance and expression can be interpolated to achieve a continuous and morphable facial synthesis. CIPS-3D: A 3D-Aware Generator of GANs Based on Conditionally-Independent Pixel Synthesis. [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. 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. (x,d)(sRx+t,d)fp,m, (a) Pretrain NeRF 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. "One of the main limitations of Neural Radiance Fields (NeRFs) is that training them requires many images and a lot of time (several days on a single GPU). To demonstrate generalization capabilities, a slight subject movement or inaccurate camera pose estimation degrades the reconstruction quality. View 4 excerpts, references background and methods.

We transfer the gradients from Dq independently of Ds. We show that even without pre-training on multi-view datasets, SinNeRF can yield photo-realistic novel-view synthesis results. Our work is a first step toward the goal that makes NeRF practical with casual captures on hand-held devices. In our experiments, applying the meta-learning algorithm designed for image classification[Tseng-2020-CDF] performs poorly for view synthesis. The subjects cover different genders, skin colors, races, hairstyles, and accessories. Active Appearance Models. In that sense, Instant NeRF could be as important to 3D as digital cameras and JPEG compression have been to 2D photography vastly increasing the speed, ease and reach of 3D capture and sharing.. InTable4, we show that the validation performance saturates after visiting 59 training tasks.

Face Transfer with Multilinear Models. These excluded regions, however, are critical for natural portrait view synthesis. Recent research indicates that we can make this a lot faster by eliminating deep learning. Edgar Tretschk, Ayush Tewari, Vladislav Golyanik, Michael Zollhfer, Christoph Lassner, and Christian Theobalt. This allows the network to be trained across multiple scenes to learn a scene prior, enabling it to perform novel view synthesis in a feed-forward manner from a sparse set of views (as few as one). By clicking accept or continuing to use the site, you agree to the terms outlined in our. 2020. 2019. 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. 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). In all cases, pixelNeRF outperforms current state-of-the-art baselines for novel view synthesis and single image 3D reconstruction. 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.

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. Today, AI researchers are working on the opposite: turning a collection of still images into a digital 3D scene in a matter of seconds. In Proc. Abstract: Reasoning the 3D structure of a non-rigid dynamic scene from a single moving camera is an under-constrained problem. Unlike previous few-shot NeRF approaches, our pipeline is unsupervised, capable of being trained with independent images without 3D, multi-view, or pose supervision. We present a method for estimating Neural Radiance Fields (NeRF) from a single headshot portrait. Semantic Deep Face Models. Without warping to the canonical face coordinate, the results using the world coordinate inFigure10(b) show artifacts on the eyes and chins. While NeRF has demonstrated high-quality view synthesis, it requires multiple images of static scenes and thus impractical for casual captures and moving subjects. GIRAFFE: Representing Scenes as Compositional Generative Neural Feature Fields. Applications of our pipeline include 3d avatar generation, object-centric novel view synthesis with a single input image, and 3d-aware super-resolution, to name a few.

We conduct extensive experiments on ShapeNet benchmarks for single image novel view synthesis tasks with held-out objects as well as entire unseen categories. The margin decreases when the number of input views increases and is less significant when 5+ input views are available. Discussion. Amit Raj, Michael Zollhoefer, Tomas Simon, Jason Saragih, Shunsuke Saito, James Hays, and Stephen Lombardi. We show that compensating the shape variations among the training data substantially improves the model generalization to unseen subjects. Chen Gao, Yi-Chang Shih, Wei-Sheng Lai, Chia-Kai Liang, Jia-Bin Huang: Portrait Neural Radiance Fields from a Single Image. 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. While NeRF has demonstrated high-quality view synthesis, it requires multiple images of static scenes and thus impractical for casual captures and moving subjects. 33. However, training the MLP requires capturing images of static subjects from multiple viewpoints (in the order of 10-100 images)[Mildenhall-2020-NRS, Martin-2020-NIT]. Then, we finetune the pretrained model parameter p by repeating the iteration in(1) for the input subject and outputs the optimized model parameter s. Abstract. Portrait view synthesis enables various post-capture edits and computer vision applications, 8649-8658. NeRF: Representing Scenes as Neural Radiance Fields for View Synthesis.

We present a method for estimating Neural Radiance Fields (NeRF) from a single headshot portrait. A style-based generator architecture for generative adversarial networks. ICCV. 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. We take a step towards resolving these shortcomings by . 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. CVPR. 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. 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.

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]. Chia-Kai Liang, Jia-Bin Huang: Portrait Neural Radiance Fields from a Single . Learning Compositional Radiance Fields of Dynamic Human Heads. 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. 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. BaLi-RF: Bandlimited Radiance Fields for Dynamic Scene Modeling. Emilien Dupont and Vincent Sitzmann for helpful discussions. Our experiments show favorable quantitative results against the state-of-the-art 3D face reconstruction and synthesis algorithms on the dataset of controlled captures. 2020. Pretraining on Dq. In this work, we propose to pretrain the weights of a multilayer perceptron (MLP), which implicitly models the volumetric density and colors, with a meta-learning framework using a light stage portrait dataset. Ablation study on canonical face coordinate. Our goal is to pretrain a NeRF model parameter p that can easily adapt to capturing the appearance and geometry of an unseen subject. MoRF allows for morphing between particular identities, synthesizing arbitrary new identities, or quickly generating a NeRF from few images of a new subject, all while providing realistic and consistent rendering under novel viewpoints. Our method precisely controls the camera pose, and faithfully reconstructs the details from the subject, as shown in the insets. 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. When the face pose in the inputs are slightly rotated away from the frontal view, e.g., the bottom three rows ofFigure5, our method still works well. Single-Shot High-Quality Facial Geometry and Skin Appearance Capture. Peng Zhou, Lingxi Xie, Bingbing Ni, and Qi Tian. Existing approaches condition neural radiance fields (NeRF) on local image features, projecting points to the input image plane, and aggregating 2D features to perform volume rendering. Figure2 illustrates the overview of our method, which consists of the pretraining and testing stages. At the finetuning stage, we compute the reconstruction loss between each input view and the corresponding prediction. 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. Black. (pdf) Articulated A second emerging trend is the application of neural radiance field for articulated models of people, or cats : . 2021. ICCV. involves optimizing the representation to every scene independently, requiring many calibrated views and significant compute time. 2020. Semantic Scholar is a free, AI-powered research tool for scientific literature, based at the Allen Institute for AI. 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. NeurIPS. 2021. pi-GAN: Periodic Implicit Generative Adversarial Networks for 3D-Aware Image Synthesis. Existing methods require tens to hundreds of photos to train a scene-specific NeRF network. A parametrization issue involved in applying NeRF to 360 captures of objects within large-scale, unbounded 3D scenes is addressed, and the method improves view synthesis fidelity in this challenging scenario. Copyright 2023 ACM, Inc. MoRF: Morphable Radiance Fields for Multiview Neural Head Modeling. 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). PlenOctrees for Real-time Rendering of Neural Radiance Fields. Our results faithfully preserve the details like skin textures, personal identity, and facial expressions from the input. Extensive experiments are conducted on complex scene benchmarks, including NeRF synthetic dataset, Local Light Field Fusion dataset, and DTU dataset. 2020. At the test time, only a single frontal view of the subject s is available. 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]. Our pretraining inFigure9(c) outputs the best results against the ground truth. 2020. 2019. 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. To improve the generalization to unseen faces, we train the MLP in the canonical coordinate space approximated by 3D face morphable models. Specifically, we leverage gradient-based meta-learning for pretraining a NeRF model so that it can quickly adapt using light stage captures as our meta-training dataset. While NeRF has demonstrated high-quality view synthesis, it requires multiple images of static scenes and thus impractical for casual captures and moving subjects. 2021.
