- Computer ScienceIEEE International Conference on Computer Vision
- 25 November 2020
This work presents the first method capable of photorealistically reconstructing deformable scenes using photos/videos captured casually from mobile phones and shows that it faithfully reconstructs non-rigidly deforming scenes and reproduces unseen views with high fidelity.

This paper proposes a novel mesh normal filtering framework based on the joint bilateral filter, with applications in mesh denoising, and compute the guidance normal on a face using a neighboring patch with the most consistent normal orientations, which provides a reliable estimation of the true normal even with a high‐level of noise.
Realtime performance-based facial animation
- T. Weise, Sofien Bouaziz, Hao Li, Mark Pauly
- Computer ScienceACM Transactions on Graphics
- 1 July 2011
A novel face tracking algorithm that combines geometry and texture registration with pre-recorded animation priors in a single optimization is introduced that demonstrates that compelling 3D facial dynamics can be reconstructed in realtime without the use of face markers, intrusive lighting, or complex scanning hardware.
HyperNeRF: A Higher-Dimensional Representation for Topologically Varying Neural Radiance Fields
- Keunhong Park, U. Sinha, S. Seitz
- BiologyArXiv
- 24 June 2021
By modeling a family of shapes in a high dimensional space, the Hyper-NeRF model is able to handle topological variation and thereby produce more realistic renderings and more accurate geometric reconstructions, as can be seen in (b).
Projective dynamics

- 1 August 2012
A unified optimization framework for geometry processing based on shape constraints provides a systematic way of building new solvers for geometryprocessing and produces similar or better results than state‐of‐the‐art methods.
Online modeling for realtime facial animation
- Sofien Bouaziz, Yangang Wang, Mark Pauly
