ADOP: Approximate Differentiable One-Pixel Point Rendering

2 code implementations13 Oct 2021 Darius Rückert, Linus Franke, Marc Stamminger

Like other neural renderers, our system takes as input calibrated camera images and a proxy geometry of the scene, in our case a point cloud.

Face2Face: Real-time Face Capture and Reenactment of RGB Videos

no code implementations CVPR 2016 Justus Thies, Michael Zollhöfer, Marc Stamminger, Christian Theobalt, Matthias Nießner

Our goal is to animate the facial expressions of the target video by a source actor and re-render the manipulated output video in a photo-realistic fashion.

Image-guided Neural Object Rendering

no code implementations ICLR 2020 Justus Thies, Michael Zollhöfer, Christian Theobalt, Marc Stamminger, Matthias Nießner

Based on this 3D proxy, the appearance of a captured view can be warped into a new target view as in classical image-based rendering.

LumiPath -- Towards Real-time Physically-based Rendering on Embedded Devices

1 code implementation9 Mar 2019 Laura Fink, Sing Chun Lee, Jie Ying Wu, Xingtong Liu, Tianyu Song, Yordanka Stoyanova, Marc Stamminger, Nassir Navab, Mathias Unberath

With the increasing computational power of today's workstations, real-time physically-based rendering is within reach, rapidly gaining attention across a variety of domains.

NRMVS: Non-Rigid Multi-View Stereo

no code implementations12 Jan 2019 Matthias Innmann, Kihwan Kim, Jinwei Gu, Matthias Niessner, Charles Loop, Marc Stamminger, Jan Kautz

We show that creating a dense 4D structure from a few RGB images with non-rigid changes is possible, and demonstrate that our method can be used to interpolate novel deformed scenes from various combinations of these deformation estimates derived from the sparse views.

IGNOR: Image-guided Neural Object Rendering

no code implementations26 Nov 2018 Justus Thies, Michael Zollhöfer, Christian Theobalt, Marc Stamminger, Matthias Nießner

Based on this 3D proxy, the appearance of a captured view can be warped into a new target view as in classical image-based rendering.

HeadOn: Real-time Reenactment of Human Portrait Videos

no code implementations29 May 2018 Justus Thies, Michael Zollhöfer, Christian Theobalt, Marc Stamminger, Matthias Nießner

We propose HeadOn, the first real-time source-to-target reenactment approach for complete human portrait videos that enables transfer of torso and head motion, face expression, and eye gaze.

FaceVR: Real-Time Facial Reenactment and Eye Gaze Control in Virtual Reality

no code implementations11 Oct 2016 Justus Thies, Michael Zollhöfer, Marc Stamminger, Christian Theobalt, Matthias Nießner

Based on reenactment of a prerecorded stereo video of the person without the HMD, FaceVR incorporates photo-realistic re-rendering in real time, thus allowing artificial modifications of face and eye appearances.

VolumeDeform: Real-time Volumetric Non-rigid Reconstruction

no code implementations27 Mar 2016 Matthias Innmann, Michael Zollhöfer, Matthias Nießner, Christian Theobalt, Marc Stamminger

We cast finding the optimal deformation of space as a non-linear regularized variational optimization problem by enforcing local smoothness and proximity to the input constraints.
