Enhancing Photorealism Enhancement

no code implementations10 May 2021 Stephan R. Richter, Hassan Abu Alhaija, Vladlen Koltun

We confirm the benefits of our contributions in controlled experiments and report substantial gains in stability and realism in comparison to recent image-to-image translation methods and a variety of other baselines.

MeshSDF: Differentiable Iso-Surface Extraction

1 code implementation NeurIPS 2020 Edoardo Remelli, Artem Lukoianov, Stephan R. Richter, Benoît Guillard, Timur Bagautdinov, Pierre Baque, Pascal Fua

Unfortunately, these methods are often not suitable for applications that require an explicit mesh-based surface representation because converting an implicit field to such a representation relies on the Marching Cubes algorithm, which cannot be differentiated with respect to the underlying implicit field.

Matryoshka Networks: Predicting 3D Geometry via Nested Shape Layers

2 code implementations CVPR 2018 Stephan R. Richter, Stefan Roth

We scale this baseline to higher resolutions by proposing a memory-efficient shape encoding, which recursively decomposes a 3D shape into nested shape layers, similar to the pieces of a Matryoshka doll.

Playing for Data: Ground Truth from Computer Games

1 code implementation7 Aug 2016 Stephan R. Richter, Vibhav Vineet, Stefan Roth, Vladlen Koltun

Recent progress in computer vision has been driven by high-capacity models trained on large datasets.
