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. https://dl.acm.org/doi/10.1145/3528233.3530753. Our method produces a full reconstruction, covering not only the facial area but also the upper head, hairs, torso, and accessories such as eyeglasses. CIPS-3D: A 3D-Aware Generator of GANs Based on Conditionally-Independent Pixel Synthesis. We assume that the order of applying the gradients learned from Dq and Ds are interchangeable, similarly to the first-order approximation in MAML algorithm[Finn-2017-MAM]. Our method using (c) canonical face coordinate shows better quality than using (b) world coordinate on chin and eyes. Using 3D morphable model, they apply facial expression tracking. We loop through K subjects in the dataset, indexed by m={0,,K1}, and denote the model parameter pretrained on the subject m as p,m. InTable4, we show that the validation performance saturates after visiting 59 training tasks. We address the variation by normalizing the world coordinate to the canonical face coordinate using a rigid transform and train a shape-invariant model representation (Section3.3). Peng Zhou, Lingxi Xie, Bingbing Ni, and Qi Tian. 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. Creating a 3D scene with traditional methods takes hours or longer, depending on the complexity and resolution of the visualization. SIGGRAPH) 39, 4, Article 81(2020), 12pages. Our training data consists of light stage captures over multiple subjects. (b) When the input is not a frontal view, the result shows artifacts on the hairs. NeurIPS.

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 Siggraph, Vol. TL;DR: Given only a single reference view as input, our novel semi-supervised framework trains a neural radiance field effectively. 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. Black, Hao Li, and Javier Romero. Specifically, for each subject m in the training data, we compute an approximate facial geometry Fm from the frontal image using a 3D morphable model and image-based landmark fitting[Cao-2013-FA3]. We validate the design choices via ablation study and show that our method enables natural portrait view synthesis compared with state of the arts. At the test time, only a single frontal view of the subject s is available. We presented a method for portrait view synthesis using a single headshot photo. It may not reproduce exactly the results from the paper. Recent research work has developed powerful generative models (e.g., StyleGAN2) that can synthesize complete human head images with impressive photorealism, enabling applications such as photorealistically editing real photographs. 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. Graph. It is a novel, data-driven solution to the long-standing problem in computer graphics of the realistic rendering of virtual worlds. In each row, we show the input frontal view and two synthesized views using. Our results improve when more views are available. Learning Compositional Radiance Fields of Dynamic Human Heads.
