Kernel Aware Resampler

no code implementations CVPR 2023 Michael Bernasconi, Abdelaziz Djelouah, Farnood Salehi, Markus Gross, Christopher Schroers

This renders our model applicable for different types of data not seen during the training such as normals.

Frame Interpolation Transformer and Uncertainty Guidance

no code implementations CVPR 2023 Markus Plack, Karlis Martins Briedis, Abdelaziz Djelouah, Matthias B. Hullin, Markus Gross, Christopher Schroers

Through this error estimation, our method can produce even higher-quality intermediate frames using only a fraction of the time compared to a full rendering.

Blind Image Restoration with Flow Based Priors

no code implementations9 Sep 2020 Leonhard Helminger, Michael Bernasconi, Abdelaziz Djelouah, Markus Gross, Christopher Schroers

In contrast to this, we propose using normalizing flows to model the distribution of the target content and to use this as a prior in a maximum a posteriori (MAP) formulation.

Lossy Image Compression with Normalizing Flows

no code implementations ICLR Workshop Neural_Compression 2021 Leonhard Helminger, Abdelaziz Djelouah, Markus Gross, Christopher Schroers

However, state-of-the-art solutions for deep image compression typically employ autoencoders which map the input to a lower dimensional latent space and thus irreversibly discard information already before quantization.

Neural Inter-Frame Compression for Video Coding

no code implementations ICCV 2019 Abdelaziz Djelouah, Joaquim Campos, Simone Schaub-Meyer, Christopher Schroers

We propose to compute residuals directly in latent space instead of in pixel space as this allows to reuse the same image compression network for both key frames and intermediate frames.

Content Adaptive Optimization for Neural Image Compression

no code implementations4 Jun 2019 Joaquim Campos, Simon Meierhans, Abdelaziz Djelouah, Christopher Schroers

The field of neural image compression has witnessed exciting progress as recently proposed architectures already surpass the established transform coding based approaches.

Disentangled Dynamic Representations from Unordered Data

no code implementations10 Dec 2018 Leonhard Helminger, Abdelaziz Djelouah, Markus Gross, Romann M. Weber

We present a deep generative model that learns disentangled static and dynamic representations of data from unordered input.

Deep Video Color Propagation

no code implementations9 Aug 2018 Simone Meyer, Victor Cornillère, Abdelaziz Djelouah, Christopher Schroers, Markus Gross

Traditional approaches for color propagation in videos rely on some form of matching between consecutive video frames.

Normalized Cut Loss for Weakly-supervised CNN Segmentation

no code implementations CVPR 2018 Meng Tang, Abdelaziz Djelouah, Federico Perazzi, Yuri Boykov, Christopher Schroers

Our normalized cut loss approach to segmentation brings the quality of weakly-supervised training significantly closer to fully supervised methods.

PhaseNet for Video Frame Interpolation

no code implementations CVPR 2018 Simone Meyer, Abdelaziz Djelouah, Brian McWilliams, Alexander Sorkine-Hornung, Markus Gross, Christopher Schroers

We show that this is superior to the hand-crafted heuristics previously used in phase-based methods and also compares favorably to recent deep learning based approaches for video frame interpolation on challenging datasets.

On Regularized Losses for Weakly-supervised CNN Segmentation

no code implementations ECCV 2018 Meng Tang, Federico Perazzi, Abdelaziz Djelouah, Ismail Ben Ayed, Christopher Schroers, Yuri Boykov

This approach simplifies weakly-supervised training by avoiding extra MRF/CRF inference steps or layers explicitly generating full masks, while improving both the quality and efficiency of training.
