Model-aware 3D Eye Gaze from Weak and Few-shot Supervisions

1 code implementation20 Nov 2023 Nikola Popovic, Dimitrios Christodoulou, Danda Pani Paudel, Xi Wang, Luc van Gool

In this work, we propose to predict 3D eye gaze from weak supervision of eye semantic segmentation masks and direct supervision of a few 3D gaze vectors.

Surface Normal Clustering for Implicit Representation of Manhattan Scenes

1 code implementation ICCV 2023 Nikola Popovic, Danda Pani Paudel, Luc van Gool

In this work, we aim to leverage the geometric prior of Manhattan scenes to improve the implicit neural radiance field representations.

Gradient Obfuscation Checklist Test Gives a False Sense of Security

no code implementations3 Jun 2022 Nikola Popovic, Danda Pani Paudel, Thomas Probst, Luc van Gool

It has since become a trend to use these five characteristics as a sufficient test, to determine whether or not gradient obfuscation is the main source of robustness.

Spatially Multi-conditional Image Generation

no code implementations25 Mar 2022 Ritika Chakraborty, Nikola Popovic, Danda Pani Paudel, Thomas Probst, Luc van Gool

However, multi-conditional image generation is a very challenging problem due to the heterogeneity and the sparsity of the (in practice) available conditioning labels.

Improving the Behaviour of Vision Transformers with Token-consistent Stochastic Layers

no code implementations30 Dec 2021 Nikola Popovic, Danda Pani Paudel, Thomas Probst, Luc van Gool

We use linear layers with token-consistent stochastic parameters inside the multilayer perceptron blocks, without altering the architecture of the transformer.

Jump-induced mixed-mode oscillations through piecewise-affine maps

no code implementations9 Mar 2021 Yiorgos Patsios, Renato Huzak, Nikola Popovic, Peter De Maesschalck

Mixed-mode oscillations (MMOs) are complex oscillatory patterns in which large-amplitude relaxation oscillations (LAOs) alternate with small-amplitude oscillations (SAOs).

CompositeTasking: Understanding Images by Spatial Composition of Tasks

1 code implementation CVPR 2021 Nikola Popovic, Danda Pani Paudel, Thomas Probst, Guolei Sun, Luc van Gool

Learning to perform spatially distributed tasks is motivated by the frequent availability of only sparse labels across tasks, and the desire for a compact multi-tasking network.
