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. http://aaronsplace.co.uk/papers/jackson2017recon. Portrait Neural Radiance Fields from a Single Image Learning a Model of Facial Shape and Expression from 4D Scans. IEEE Trans. Portraits taken by wide-angle cameras exhibit undesired foreshortening distortion due to the perspective projection [Fried-2016-PAM, Zhao-2019-LPU]. Initialization. Input views in test time. While estimating the depth and appearance of an object based on a partial view is a natural skill for humans, its a demanding task for AI. Our method takes a lot more steps in a single meta-training task for better convergence. PAMI 23, 6 (jun 2001), 681685. Google Scholar The warp makes our method robust to the variation in face geometry and pose in the training and testing inputs, as shown inTable3 andFigure10. Despite the rapid development of Neural Radiance Field (NeRF), the necessity of dense covers largely prohibits its wider applications. It is thus impractical for portrait view synthesis because 2019. Our method requires the input subject to be roughly in frontal view and does not work well with the profile view, as shown inFigure12(b). 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. While NeRF has demonstrated high-quality view synthesis, it requires multiple images of static scenes and thus impractical for casual captures and moving subjects. In contrast, our method requires only one single image as input. Users can use off-the-shelf subject segmentation[Wadhwa-2018-SDW] to separate the foreground, inpaint the background[Liu-2018-IIF], and composite the synthesized views to address the limitation. Despite the rapid development of Neural Radiance Field (NeRF), the necessity of dense covers largely prohibits its wider applications. Ablation study on different weight initialization. Alex Yu, Ruilong Li, Matthew Tancik, Hao Li, Ren Ng, and Angjoo Kanazawa. 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. Comparison to the state-of-the-art portrait view synthesis on the light stage dataset. The videos are accompanied in the supplementary materials. 2021. 24, 3 (2005), 426433.

Compared to the majority of deep learning face synthesis works, e.g.,[Xu-2020-D3P], which require thousands of individuals as the training data, the capability to generalize portrait view synthesis from a smaller subject pool makes our method more practical to comply with the privacy requirement on personally identifiable information. We leverage gradient-based meta-learning algorithms[Finn-2017-MAM, Sitzmann-2020-MML] to learn the weight initialization for the MLP in NeRF from the meta-training tasks, i.e., learning a single NeRF for different subjects in the light stage dataset. To balance the training size and visual quality, we use 27 subjects for the results shown in this paper. producing reasonable results when given only 1-3 views at inference time. Learning Compositional Radiance Fields of Dynamic Human Heads. To validate the face geometry learned in the finetuned model, we render the (g) disparity map for the front view (a). By virtually moving the camera closer or further from the subject and adjusting the focal length correspondingly to preserve the face area, we demonstrate perspective effect manipulation using portrait NeRF inFigure8 and the supplemental video. We validate the design choices via ablation study and show that our method enables natural portrait view synthesis compared with state of the arts. Copyright 2023 ACM, Inc.

A style-based generator architecture for generative adversarial networks. CVPR. 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). Our method preserves temporal coherence in challenging areas like hairs and occlusion, such as the nose and ears. 2022. A parametrization issue involved in applying NeRF to 360 captures of objects within large-scale, unbounded 3D scenes is addressed, and the method improves view synthesis fidelity in this challenging scenario.

Alias-Free Generative Adversarial Networks. Comparisons. Single-Shot High-Quality Facial Geometry and Skin Appearance Capture. While NeRF has demonstrated high-quality view synthesis, it requires multiple images of static scenes and thus impractical for casual captures and moving subjects.

While NeRF has demonstrated high-quality view synthesis, it requires multiple images of static scenes and thus impractical for casual captures and moving subjects. Neural Scene Flow Fields for Space-Time View Synthesis of Dynamic Scenes. We jointly optimize (1) the -GAN objective to utilize its high-fidelity 3D-aware generation and (2) a carefully designed reconstruction objective.

We take a step towards resolving these shortcomings by . However, using a nave pretraining process that optimizes the reconstruction error between the synthesized views (using the MLP) and the rendering (using the light stage data) over the subjects in the dataset performs poorly for unseen subjects due to the diverse appearance and shape variations among humans.

ACM Trans. To manage your alert preferences, click on the button below. Are you sure you want to create this branch? We present a method for estimating Neural Radiance Fields (NeRF) from a single headshot portrait. Creating a 3D scene with traditional methods takes hours or longer, depending on the complexity and resolution of the visualization. Addressing the finetuning speed and leveraging the stereo cues in dual camera popular on modern phones can be beneficial to this goal. 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. 2020. Our method outputs a more natural look on face inFigure10(c), and performs better on quality metrics against ground truth across the testing subjects, as shown inTable3. C. Liang, and J.
