Real-Time Neural Materials using Block-Compressed Features

no code implementations26 Oct 2023 Clément Weinreich, Louis de Oliveira, Antoine Houdard, Georges Nader

We present a neural material model whose features and decoder are specifically designed to be used in real-time rendering pipelines.

Inverse problem regularization with hierarchical variational autoencoders

1 code implementation ICCV 2023 Jean Prost, Antoine Houdard, Andrés Almansa, Nicolas Papadakis

Our experiments show that the proposed PnP-HVAE method is competitive with both SOTA denoiser-based PnP approaches, and other SOTA restoration methods based on generative models.

Image Restoration

Wasserstein Patch Prior for Image Superresolution

1 code implementation27 Sep 2021 Johannes Hertrich, Antoine Houdard, Claudia Redenbach

Then, the proposed regularizer penalizes the $W_2$-distance of the patch distribution of the reconstruction to the patch distribution of some reference image at different scales.

Learning local regularization for variational image restoration

no code implementations11 Feb 2021 Jean Prost, Antoine Houdard, Andrés Almansa, Nicolas Papadakis

In this work, we propose a framework to learn a local regularization model for solving general image restoration problems.

On the Existence of Optimal Transport Gradient for Learning Generative Models

no code implementations10 Feb 2021 Antoine Houdard, Arthur Leclaire, Nicolas Papadakis, Julien Rabin

Training of WGAN relies on a theoretical background: the calculation of the gradient of the optimal transport cost with respect to the generative model parameters.
