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 report the quantitative evaluation using PSNR, SSIM, and LPIPS[zhang2018unreasonable] against the ground truth inTable1. While NeRF has demonstrated high-quality view synthesis, it requires multiple images of static scenes and thus impractical for casual captures and moving subjects. The ACM Digital Library is published by the Association for Computing Machinery. ICCV. Without warping to the canonical face coordinate, the results using the world coordinate inFigure10(b) show artifacts on the eyes and chins. View 4 excerpts, references background and methods. (c) Finetune. Pix2NeRF: Unsupervised Conditional -GAN for Single Image to Neural Radiance Fields Translation Portrait Neural Radiance Fields from a Single Image , denoted as LDs(fm). 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). In Proc. We transfer the gradients from Dq independently of Ds. Space-time Neural Irradiance Fields for Free-Viewpoint Video . The high diversities among the real-world subjects in identities, facial expressions, and face geometries are challenging for training. In Proc. 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 results faithfully preserve the details like skin textures, personal identity, and facial expressions from the input. 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. Mixture of Volumetric Primitives (MVP), a representation for rendering dynamic 3D content that combines the completeness of volumetric representations with the efficiency of primitive-based rendering, is presented. At the finetuning stage, we compute the reconstruction loss between each input view and the corresponding prediction. [Jackson-2017-LP3] only covers the face area. In Proc. We present a method for estimating Neural Radiance Fields (NeRF) from a single headshot portrait. 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. ICCV. We do not require the mesh details and priors as in other model-based face view synthesis[Xu-2020-D3P, Cao-2013-FA3]. \underbracket\pagecolorwhite(a)Input \underbracket\pagecolorwhite(b)Novelviewsynthesis \underbracket\pagecolorwhite(c)FOVmanipulation. such as pose manipulation[Criminisi-2003-GMF], Graphics (Proc. Bringing AI into the picture speeds things up. 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. 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. Separately, we apply a pretrained model on real car images after background removal. 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].

We are interested in generalizing our method to class-specific view synthesis, such as cars or human bodies. Addressing the finetuning speed and leveraging the stereo cues in dual camera popular on modern phones can be beneficial to this goal. Generating 3D faces using Convolutional Mesh Autoencoders. We show that even without pre-training on multi-view datasets, SinNeRF can yield photo-realistic novel-view synthesis results. [Jackson-2017-LP3] using the official implementation111 http://aaronsplace.co.uk/papers/jackson2017recon. it can represent scenes with multiple objects, where a canonical space is unavailable, Guy Gafni, Justus Thies, Michael Zollhfer, and Matthias Niener.

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]. 40, 6 (dec 2021). sign in We finetune the pretrained weights learned from light stage training data[Debevec-2000-ATR, Meka-2020-DRT] for unseen inputs. In Proc. 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. 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. Using a new input encoding method, researchers can achieve high-quality results using a tiny neural network that runs rapidly. CVPR. Second, we propose to train the MLP in a canonical coordinate by exploiting domain-specific knowledge about the face shape. Daniel Roich, Ron Mokady, AmitH Bermano, and Daniel Cohen-Or.

Discussion. Instances should be directly within these three folders. Learning Compositional Radiance Fields of Dynamic Human Heads. We introduce the novel CFW module to perform expression conditioned warping in 2D feature space, which is also identity adaptive and 3D constrained. Inspired by the remarkable progress of neural radiance fields (NeRFs) in photo-realistic novel view synthesis of static scenes, extensions have been proposed for . 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. View synthesis with neural implicit representations. A Decoupled 3D Facial Shape Model by Adversarial Training. We demonstrate foreshortening correction as applications[Zhao-2019-LPU, Fried-2016-PAM, Nagano-2019-DFN]. While NeRF has demonstrated high-quality view synthesis, it requires multiple images of static scenes and thus impractical for casual captures and moving subjects.

Jiatao Gu, Lingjie Liu, Peng Wang, and Christian Theobalt. Vol. arxiv:2108.04913[cs.CV]. Existing single-image view synthesis methods model the scene with point cloud[niklaus20193d, Wiles-2020-SEV], multi-plane image[Tucker-2020-SVV, huang2020semantic], or layered depth image[Shih-CVPR-3Dphoto, Kopf-2020-OS3]. 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. This is a challenging task, as training NeRF requires multiple views of the same scene, coupled with corresponding poses, which are hard to obtain. Non-Rigid Neural Radiance Fields: Reconstruction and Novel View Synthesis of a Dynamic Scene From Monocular Video. We present a method for estimating Neural Radiance Fields (NeRF) from a single headshot portrait. 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. 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. We average all the facial geometries in the dataset to obtain the mean geometry F. 1280312813. Visit the NVIDIA Technical Blog for a tutorial on getting started with Instant NeRF. 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. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Our method can also seemlessly integrate multiple views at test-time to obtain better results. CVPR. (a) When the background is not removed, our method cannot distinguish the background from the foreground and leads to severe artifacts. arXiv Vanity renders academic papers from Render videos and create gifs for the three datasets: python render_video_from_dataset.py --path PRETRAINED_MODEL_PATH --output_dir OUTPUT_DIRECTORY --curriculum "celeba" --dataset_path "/PATH/TO/img_align_celeba/" --trajectory "front", python render_video_from_dataset.py --path PRETRAINED_MODEL_PATH --output_dir OUTPUT_DIRECTORY --curriculum "carla" --dataset_path "/PATH/TO/carla/*.png" --trajectory "orbit", python render_video_from_dataset.py --path PRETRAINED_MODEL_PATH --output_dir OUTPUT_DIRECTORY --curriculum "srnchairs" --dataset_path "/PATH/TO/srn_chairs/" --trajectory "orbit".

The existing approach for constructing neural radiance fields [Mildenhall et al. 2015. 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. Graphics (Proc. Check if you have access through your login credentials or your institution to get full access on this article. Our method produces a full reconstruction, covering not only the facial area but also the upper head, hairs, torso, and accessories such as eyeglasses. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Canonical face coordinate. It is thus impractical for portrait view synthesis because The process, however, requires an expensive hardware setup and is unsuitable for casual users. We quantitatively evaluate the method using controlled captures and demonstrate the generalization to real portrait images, showing favorable results against state-of-the-arts. 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. We show the evaluations on different number of input views against the ground truth inFigure11 and comparisons to different initialization inTable5. Face Transfer with Multilinear Models. 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. Work fast with our official CLI. Known as inverse rendering, the process uses AI to approximate how light behaves in the real world, enabling researchers to reconstruct a 3D scene from a handful of 2D images taken at different angles. Copy img_csv/CelebA_pos.csv to /PATH_TO/img_align_celeba/. Instant NeRF, however, cuts rendering time by several orders of magnitude. The learning-based head reconstruction method from Xuet al. At the test time, only a single frontal view of the subject s is available.
