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. It is thus impractical for portrait view synthesis because Pretraining on Ds. 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. Terrance DeVries, MiguelAngel Bautista, Nitish Srivastava, GrahamW. Taylor, and JoshuaM. Susskind. We show that our method can also conduct wide-baseline view synthesis on more complex real scenes from the DTU MVS dataset, 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. Our method using (c) canonical face coordinate shows better quality than using (b) world coordinate on chin and eyes. 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.

Pix2NeRF: Unsupervised Conditional -GAN for Single Image to Neural Radiance Fields Translation If theres too much motion during the 2D image capture process, the AI-generated 3D scene will be blurry. We show that even whouzt pre-training on multi-view datasets, SinNeRF can yield photo-realistic novel-view synthesis results. 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. Volker Blanz and Thomas Vetter. SIGGRAPH '22: ACM SIGGRAPH 2022 Conference Proceedings. We show that, unlike existing methods, one does not need multi-view . Existing single-image methods use the symmetric cues[Wu-2020-ULP], morphable model[Blanz-1999-AMM, Cao-2013-FA3, Booth-2016-A3M, Li-2017-LAM], mesh template deformation[Bouaziz-2013-OMF], and regression with deep networks[Jackson-2017-LP3]. to use Codespaces. In Proc. View synthesis with neural implicit representations. Our approach operates in view-spaceas opposed to canonicaland requires no test-time optimization. The optimization iteratively updates the tm for Ns iterations as the following: where 0m=p,m1, m=Ns1m, and is the learning rate. PVA: Pixel-aligned Volumetric Avatars. At the test time, we initialize the NeRF with the pretrained model parameter p and then finetune it on the frontal view for the input subject s. 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. 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. 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. sign in Chia-Kai Liang, Jia-Bin Huang: Portrait Neural Radiance Fields from a Single .

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]. 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. (b) When the input is not a frontal view, the result shows artifacts on the hairs. 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. 2019. (a) When the background is not removed, our method cannot distinguish the background from the foreground and leads to severe artifacts. While NeRF has demonstrated high-quality view synthesis, it requires multiple images of static scenes and thus impractical for casual captures and moving subjects. IEEE. 2021a. In Proc. 2018.

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. 99. Without warping to the canonical face coordinate, the results using the world coordinate inFigure10(b) show artifacts on the eyes and chins. Beyond NeRFs, NVIDIA researchers are exploring how this input encoding technique might be used to accelerate multiple AI challenges including reinforcement learning, language translation and general-purpose deep learning algorithms. ACM Trans. During the training, we use the vertex correspondences between Fm and F to optimize a rigid transform by the SVD decomposition (details in the supplemental documents). 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. 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. . 2015. 2020.

ACM Trans. 2020] To validate the face geometry learned in the finetuned model, we render the (g) disparity map for the front view (a). This is a challenging task, as training NeRF requires multiple views of the same scene, coupled with corresponding poses, which are hard to obtain. [11] K. Genova, F. Cole, A. Sud, A. Sarna, and T. Funkhouser (2020) Local deep implicit functions for 3d . Our method can also seemlessly integrate multiple views at test-time to obtain better results. 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. Zhengqi Li, Simon Niklaus, Noah Snavely, and Oliver Wang. 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. 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). 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. Portrait Neural Radiance Fields from a Single Image. 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 provide a multi-view portrait dataset consisting of controlled captures in a light stage. Similarly to the neural volume method[Lombardi-2019-NVL], our method improves the rendering quality by sampling the warped coordinate from the world coordinates.
