portrait neural radiance fields from a single image

In contrast, our method requires only one single image as input. 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]. Left and right in (a) and (b): input and output of our method. 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. Copy img_csv/CelebA_pos.csv to /PATH_TO/img_align_celeba/. In each row, we show the input frontal view and two synthesized views using. 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 demonstrate foreshortening correction as applications[Zhao-2019-LPU, Fried-2016-PAM, Nagano-2019-DFN]. Tianye Li, Timo Bolkart, MichaelJ. We take a step towards resolving these shortcomings by . Emilien Dupont and Vincent Sitzmann for helpful discussions. We refer to the process training a NeRF model parameter for subject m from the support set as a task, denoted by Tm.

Here, we demonstrate how MoRF is a strong new step forwards towards generative NeRFs for 3D neural head modeling. Moreover, it is feed-forward without requiring test-time optimization for each scene. 187194. 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. 2020. In ECCV. Alias-Free Generative Adversarial Networks. 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. ACM Trans. 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. Our method is visually similar to the ground truth, synthesizing the entire subject, including hairs and body, and faithfully preserving the texture, lighting, and expressions. Local image features were used in the related regime of implicit surfaces in, Our MLP architecture is 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 View 10 excerpts, references methods and background, 2018 IEEE/CVF Conference on Computer Vision and Pattern Recognition. 39, 5 (2020). The high diversities among the real-world subjects in identities, facial expressions, and face geometries are challenging for training. While NeRF has demonstrated high-quality view synthesis, it requires multiple images of static scenes and thus impractical for casual captures and moving subjects. 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. it can represent scenes with multiple objects, where a canonical space is unavailable, Cited by: 2. To attain this goal, we present a Single View NeRF (SinNeRF) framework consisting of thoughtfully designed semantic and geometry regularizations. 2020. 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. 2021. 8649-8658. CVPR. 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. 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. For better generalization, the gradients of Ds will be adapted from the input subject at the test time by finetuning, instead of transferred from the training data. We provide pretrained model checkpoint files for the three datasets. 40, 6, Article 238 (dec 2021). arxiv:2108.04913[cs.CV]. We present a method for estimating Neural Radiance Fields (NeRF) from a single headshot portrait. Our method precisely controls the camera pose, and faithfully reconstructs the details from the subject, as shown in the insets. We then feed the warped coordinate to the MLP network f to retrieve color and occlusion (Figure4). In Proc. 2001. For everything else, email us at [emailprotected]. PVA: Pixel-aligned Volumetric Avatars. In a scene that includes people or other moving elements, the quicker these shots are captured, the better. Our training data consists of light stage captures over multiple subjects. Please send any questions or comments to Alex Yu. 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. Portrait Neural Radiance Fields from a Single Image. Therefore, we provide a script performing hybrid optimization: predict a latent code using our model, then perform latent optimization as introduced in pi-GAN. 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. No description, website, or topics provided. 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 show that, unlike existing methods, one does not need multi-view . Render images and a video interpolating between 2 images. 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 . While NeRF has demonstrated high-quality view synthesis, it requires multiple images of static scenes and thus impractical for casual captures and moving subjects. 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. 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 build the environment, run: For CelebA, download from https://mmlab.ie.cuhk.edu.hk/projects/CelebA.html and extract the img_align_celeba split.

Using 3D morphable model, they apply facial expression tracking. CVPR. Explore our regional blogs and other social networks. Generating 3D faces using Convolutional Mesh Autoencoders. Semantic Deep Face Models. Since our model is feed-forward and uses a relatively compact latent codes, it most likely will not perform that well on yourself/very familiar faces---the details are very challenging to be fully captured by a single pass. Our method builds on recent work of neural implicit representations[sitzmann2019scene, Mildenhall-2020-NRS, Liu-2020-NSV, Zhang-2020-NAA, Bemana-2020-XIN, Martin-2020-NIT, xian2020space] for view synthesis. 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]. We present a method for estimating Neural Radiance Fields (NeRF) from a single headshot portrait. 343352. Pixel Codec Avatars. Graph. NeRFs use neural networks to represent and render realistic 3D scenes based on an input collection of 2D images. Our pretraining inFigure9(c) outputs the best results against the ground truth.

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. Ablation study on canonical face coordinate. Our method preserves temporal coherence in challenging areas like hairs and occlusion, such as the nose and ears. Given an input (a), we virtually move the camera closer (b) and further (c) to the subject, while adjusting the focal length to match the face size. View synthesis with neural implicit representations. The videos are accompanied in the supplementary materials. NeurIPS. The results from [Xu-2020-D3P] were kindly provided by the authors. In Proc. 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. Existing methods require tens to hundreds of photos to train a scene-specific NeRF network. Extensive experiments are conducted on complex scene benchmarks, including NeRF synthetic dataset, Local Light Field Fusion dataset, and DTU dataset. 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.
