After Nq iterations, we update the pretrained parameter by the following: Note that(3) does not affect the update of the current subject m, i.e.,(2), but the gradients are carried over to the subjects in the subsequent iterations through the pretrained model parameter update in(4). We do not require the mesh details and priors as in other model-based face view synthesis[Xu-2020-D3P, Cao-2013-FA3]. CVPR. The process, however, requires an expensive hardware setup and is unsuitable for casual users. We presented a method for portrait view synthesis using a single headshot photo. Graph. 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. 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. Chia-Kai Liang, Jia-Bin Huang: Portrait Neural Radiance Fields from a Single . Proc. 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. Our training data consists of light stage captures over multiple subjects. The model was developed using the NVIDIA CUDA Toolkit and the Tiny CUDA Neural Networks library. In this work, we propose to pretrain the weights of a multilayer perceptron (MLP . In Proc.

Ablation study on the number of input views during testing. 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. Please let the authors know if results are not at reasonable levels! Portrait Neural Radiance Fields from a Single Image. 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. Our method does not require a large number of training tasks consisting of many subjects. ECCV. Pivotal Tuning for Latent-based Editing of Real Images. Copyright 2023 ACM, Inc. MoRF: Morphable Radiance Fields for Multiview Neural Head Modeling. In the supplemental video, we hover the camera in the spiral path to demonstrate the 3D effect. If nothing happens, download Xcode and try again. 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]. 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]. The technology could be used to train robots and self-driving cars to understand the size and shape of real-world objects by capturing 2D images or video footage of them. The videos are accompanied in the supplementary materials. Amit Raj, Michael Zollhoefer, Tomas Simon, Jason Saragih, Shunsuke Saito, James Hays, and Stephen Lombardi. Pretraining on Dq. 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. Ablation study on different weight initialization. These excluded regions, however, are critical for natural portrait view synthesis.

Since our method requires neither canonical space nor object-level information such as masks, 2020. Nevertheless, in terms of image metrics, we significantly outperform existing methods quantitatively, as shown in the paper. A style-based generator architecture for generative adversarial networks. This is because each update in view synthesis requires gradients gathered from millions of samples across the scene coordinates and viewing directions, which do not fit into a single batch in modern GPU. Bringing AI into the picture speeds things up. p,mUpdates by (1)mUpdates by (2)Updates by (3)p,m+1. 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]. Graph. Separately, we apply a pretrained model on real car images after background removal. Cited by: 2. GRAF: Generative Radiance Fields for 3D-Aware Image Synthesis. , denoted as LDs(fm). We transfer the gradients from Dq independently of Ds. It is a novel, data-driven solution to the long-standing problem in computer graphics of the realistic rendering of virtual worlds. Unlike previous few-shot NeRF approaches, our pipeline is unsupervised, capable of being trained with independent images without 3D, multi-view, or pose supervision. Prashanth Chandran, Derek Bradley, Markus Gross, and Thabo Beeler. 2020. 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. The model requires just seconds to train on a few dozen still photos plus data on the camera angles they were taken from and can then render the resulting 3D scene within tens of milliseconds. in ShapeNet in order to perform novel-view synthesis on unseen objects. During the prediction, we first warp the input coordinate from the world coordinate to the face canonical space through (sm,Rm,tm). We also thank NVIDIA applied this approach to a popular new technology called neural radiance fields, or NeRF. Ricardo Martin-Brualla, Noha Radwan, Mehdi S.M. Sajjadi, JonathanT. Barron, Alexey Dosovitskiy, and Daniel Duckworth. Perspective manipulation. The results in (c-g) look realistic and natural. Next, we pretrain the model parameter by minimizing the L2 loss between the prediction and the training views across all the subjects in the dataset as the following: where m indexes the subject in the dataset. 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. 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. No description, website, or topics provided. In Proc. 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.
