Tarun Yenamandra, Ayush Tewari, Florian Bernard, Hans-Peter Seidel, Mohamed Elgharib, Daniel Cremers, and Christian Theobalt. This model need a portrait video and an image with only background as an inputs. Next, we pretrain the model parameter by minimizing the L2 loss between the prediction and the training views across all the subjects in the dataset as the following: where m indexes the subject in the dataset. The technique can even work around occlusions when objects seen in some images are blocked by obstructions such as pillars in other images. 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. The subjects cover different genders, skin colors, races, hairstyles, and accessories. Anurag Ranjan, Timo Bolkart, Soubhik Sanyal, and MichaelJ. To model the portrait subject, instead of using face meshes consisting only the facial landmarks, we use the finetuned NeRF at the test time to include hairs and torsos. Reconstructing face geometry and texture enables view synthesis using graphics rendering pipelines. Thanks for sharing! Extensive experiments are conducted on complex scene benchmarks, including NeRF synthetic dataset, Local Light Field Fusion dataset, and DTU dataset. Instant NeRF is a neural rendering model that learns a high-resolution 3D scene in seconds and can render images of that scene in a few milliseconds.

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]. Graph. 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). The proposed FDNeRF accepts view-inconsistent dynamic inputs and supports arbitrary facial expression editing, i.e., producing faces with novel expressions beyond the input ones, and introduces a well-designed conditional feature warping module to perform expression conditioned warping in 2D feature space. 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]. Our results look realistic, preserve the facial expressions, geometry, identity from the input, handle well on the occluded area, and successfully synthesize the clothes and hairs for the subject.

(a) When the background is not removed, our method cannot distinguish the background from the foreground and leads to severe artifacts. A tag already exists with the provided branch name. 2021. We propose pixelNeRF, a learning framework that predicts a continuous neural scene representation conditioned on one or few input images. 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. Portrait view synthesis enables various post-capture edits and computer vision applications, Abstract: Neural Radiance Fields (NeRF) achieve impressive view synthesis results for a variety of capture settings, including 360 capture of bounded scenes and forward-facing capture of bounded and unbounded scenes. The warp makes our method robust to the variation in face geometry and pose in the training and testing inputs, as shown inTable3 andFigure10. 2021. Copyright 2023 ACM, Inc.

Use Git or checkout with SVN using the web URL. We present a method for estimating Neural Radiance Fields (NeRF) from a single headshot portrait. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. 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. It is a novel, data-driven solution to the long-standing problem in computer graphics of the realistic rendering of virtual worlds. Portraits taken by wide-angle cameras exhibit undesired foreshortening distortion due to the perspective projection [Fried-2016-PAM, Zhao-2019-LPU]. The quantitative evaluations are shown inTable2. ICCV. Generating and reconstructing 3D shapes from single or multi-view depth maps or silhouette (Courtesy: Wikipedia) Neural Radiance Fields. ACM Trans. The model requires just seconds to train on a few dozen still photos plus data on the camera angles they were taken from and can then render the resulting 3D scene within tens of milliseconds. CVPR. In contrast, previous method shows inconsistent geometry when synthesizing novel views. This website is inspired by the template of Michal Gharbi. SIGGRAPH '22: ACM SIGGRAPH 2022 Conference Proceedings.
