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. 187194. Pretraining with meta-learning framework. 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. 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. CVPR. For example, Neural Radiance Fields (NeRF) demonstrates high-quality view synthesis by implicitly modeling the volumetric density and color using the weights of a multilayer perceptron (MLP). 99. When the face pose in the inputs are slightly rotated away from the frontal view, e.g., the bottom three rows ofFigure5, our method still works well. Each subject is lit uniformly under controlled lighting conditions. In contrast, our method requires only one single image as input. 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]. involves optimizing the representation to every scene independently, requiring many calibrated views and significant compute time. Rigid transform between the world and canonical face coordinate. 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.

Under the single image setting, SinNeRF significantly outperforms the . The code repo is built upon https://github.com/marcoamonteiro/pi-GAN. 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. If theres too much motion during the 2D image capture process, the AI-generated 3D scene will be blurry. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. VictoriaFernandez Abrevaya, Adnane Boukhayma, Stefanie Wuhrer, and Edmond Boyer.

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]. Collecting data to feed a NeRF is a bit like being a red carpet photographer trying to capture a celebritys outfit from every angle the neural network requires a few dozen images taken from multiple positions around the scene, as well as the camera position of each of those shots. To pretrain the MLP, we use densely sampled portrait images in a light stage capture. Left and right in (a) and (b): input and output of our method. We then feed the warped coordinate to the MLP network f to retrieve color and occlusion (Figure4). 2019. We render the support Ds and query Dq by setting the camera field-of-view to 84, a popular setting on commercial phone cameras, and sets the distance to 30cm to mimic selfies and headshot portraits taken on phone cameras. In Proc. The ACM Digital Library is published by the Association for Computing Machinery. 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. SIGGRAPH '22: ACM SIGGRAPH 2022 Conference Proceedings. SIGGRAPH) 39, 4, Article 81(2020), 12pages. CVPR. 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.
