Which Information Matters? Dissecting Human-written Multi-document Summaries with Partial Information Decomposition

Laura Mascarell, Yan L'Homme, Majed El Helou

Understanding the nature of high-quality summaries is crucial to further improve the performance of multi-document summarization. We propose an approach to characterize human-writt…

Divergence-Based Adaptive Extreme Video Completion

Majed El Helou, Ruofan Zhou, Frank Schmutz +2

Extreme image or video completion, where, for instance, we only retain 1% of pixels in random locations, allows for very cheap sampling in terms of the required pre-processing. The…

AL2: Progressive Activation Loss for Learning General Representations in Classification Neural Networks

Majed El Helou, Frederike Dümbgen, Sabine Süsstrunk

The large capacity of neural networks enables them to learn complex functions. To avoid overfitting, networks however require a lot of training data that can be expensive and time-…

Stochastic Frequency Masking to Improve Super-Resolution and Denoising Networks

Majed El Helou, Ruofan Zhou, Sabine Süsstrunk

Super-resolution and denoising are ill-posed yet fundamental image restoration tasks. In blind settings, the degradation kernel or the noise level are unknown. This makes restorati…

W2S: Microscopy Data with Joint Denoising and Super-Resolution for Widefield to SIM Mapping

Ruofan Zhou, Majed El Helou, Daniel Sage +3

In fluorescence microscopy live-cell imaging, there is a critical trade-off between the signal-to-noise ratio and spatial resolution on one side, and the integrity of the biologica…

Drone Shadow Tracking

Xiaoyan Zou, Ruofan Zhou, Majed El Helou +1

Aerial videos taken by a drone not too far above the surface may contain the drone's shadow projected on the scene. This deteriorates the aesthetic quality of videos. With the pres…
