We also address the shape variations among subjects by learning the NeRF model in canonical face space. These excluded regions, however, are critical for natural portrait view synthesis. 2020. HyperNeRF: A Higher-Dimensional Representation for Topologically Varying Neural Radiance Fields. Similarly to the neural volume method[Lombardi-2019-NVL], our method improves the rendering quality by sampling the warped coordinate from the world coordinates. Without any pretrained prior, the random initialization[Mildenhall-2020-NRS] inFigure9(a) fails to learn the geometry from a single image and leads to poor view synthesis quality. In Proc. In total, our dataset consists of 230 captures. IEEE Trans. producing reasonable results when given only 1-3 views at inference time.

While reducing the execution and training time by up to 48, the authors also achieve better quality across all scenes (NeRF achieves an average PSNR of 30.04 dB vs their 31.62 dB), and DONeRF requires only 4 samples per pixel thanks to a depth oracle network to guide sample placement, while NeRF uses 192 (64 + 128). CVPR. 2020] A morphable model for the synthesis of 3D faces. 99. 343352. 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. The existing approach for constructing neural radiance fields [Mildenhall et al. FiG-NeRF: Figure-Ground Neural Radiance Fields for 3D Object Category Modelling. While NeRF has demonstrated high-quality view synthesis, it requires multiple images of static scenes and thus impractical for casual captures and moving subjects. Pivotal Tuning for Latent-based Editing of Real Images. 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.. 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. Our work is closely related to meta-learning and few-shot learning[Ravi-2017-OAA, Andrychowicz-2016-LTL, Finn-2017-MAM, chen2019closer, Sun-2019-MTL, Tseng-2020-CDF]. 40, 6, Article 238 (dec 2021).

In a tribute to the early days of Polaroid images, NVIDIA Research recreated an iconic photo of Andy Warhol taking an instant photo, turning it into a 3D scene using Instant NeRF. In our method, the 3D model is used to obtain the rigid transform (sm,Rm,tm). 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. While NeRF has demonstrated high-quality view synthesis, it requires multiple images of static scenes and thus impractical for casual captures and moving subjects. \underbracket\pagecolorwhiteInput \underbracket\pagecolorwhiteOurmethod \underbracket\pagecolorwhiteGroundtruth. 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. Image2StyleGAN: How to embed images into the StyleGAN latent space?. 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].

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. 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]. In Proc. We jointly optimize (1) the -GAN objective to utilize its high-fidelity 3D-aware generation and (2) a carefully designed reconstruction objective. Graphics (Proc. Compared to 3D reconstruction and view synthesis for generic scenes, portrait view synthesis requires a higher quality result to avoid the uncanny valley, as human eyes are more sensitive to artifacts on faces or inaccuracy of facial appearances. Analyzing and improving the image quality of StyleGAN. IEEE, 44324441. While the outputs are photorealistic, these approaches have common artifacts that the generated images often exhibit inconsistent facial features, identity, hairs, and geometries across the results and the input image. 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. 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. The results in (c-g) look realistic and natural. 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. add losses implementation, prepare for train script push, Pix2NeRF: Unsupervised Conditional -GAN for Single Image to Neural Radiance Fields Translation (CVPR 2022), https://mmlab.ie.cuhk.edu.hk/projects/CelebA.html, https://www.dropbox.com/s/lcko0wl8rs4k5qq/pretrained_models.zip?dl=0. 2021.

Comparisons. We introduce the novel CFW module to perform expression conditioned warping in 2D feature space, which is also identity adaptive and 3D constrained. PyTorch NeRF implementation are taken from. Reconstructing the facial geometry from a single capture requires face mesh templates[Bouaziz-2013-OMF] or a 3D morphable model[Blanz-1999-AMM, Cao-2013-FA3, Booth-2016-A3M, Li-2017-LAM]. We quantitatively evaluate the method using controlled captures and demonstrate the generalization to real portrait images, showing favorable results against state-of-the-arts. We refer to the process training a NeRF model parameter for subject m from the support set as a task, denoted by Tm. To improve the generalization to unseen faces, we train the MLP in the canonical coordinate space approximated by 3D face morphable models. 2020 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR). The results from [Xu-2020-D3P] were kindly provided by the authors. Graph. To address the face shape variations in the training dataset and real-world inputs, we normalize the world coordinate to the canonical space using a rigid transform and apply f on the warped coordinate. http://aaronsplace.co.uk/papers/jackson2017recon. sign in Graphics (Proc. 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]. 2021. p,mUpdates by (1)mUpdates by (2)Updates by (3)p,m+1.

The technique can even work around occlusions when objects seen in some images are blocked by obstructions such as pillars in other images. IEEE, 81108119. SIGGRAPH) 38, 4, Article 65 (July 2019), 14pages. 2020. Novel view synthesis from a single image requires inferring occluded regions of objects and scenes whilst simultaneously maintaining semantic and physical consistency with the input. Here, we demonstrate how MoRF is a strong new step forwards towards generative NeRFs for 3D neural head modeling. Initialization. We average all the facial geometries in the dataset to obtain the mean geometry F. We show that, unlike existing methods, one does not need multi-view . 2019. 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. [Jackson-2017-LP3] only covers the face area. We conduct extensive experiments on ShapeNet benchmarks for single image novel view synthesis tasks with held-out objects as well as entire unseen categories. In Proc. 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. We manipulate the perspective effects such as dolly zoom in the supplementary materials. arXiv preprint arXiv:2106.05744(2021). Therefore, we provide a script performing hybrid optimization: predict a latent code using our model, then perform latent optimization as introduced in pi-GAN. Note that the training script has been refactored and has not been fully validated yet. 2020. Our results faithfully preserve the details like skin textures, personal identity, and facial expressions from the input. The subjects cover various ages, gender, races, and skin colors. Our method using (c) canonical face coordinate shows better quality than using (b) world coordinate on chin and eyes.
