Identifying Ethical Biases in Action Recognition Models
Ana Baltaretu, Pascal Benschop, Jan van Gemert
Human Action Recognition (HAR) models are increasingly deployed in high-stakes environments, yet their fairness across different human appearances has not been analyzed. We introdu…
Rare-Aware Autoencoding: Reconstructing Spatially Imbalanced Data
Alejandro Castañeda Garcia, Jan van Gemert, Daan Brinks +1
Autoencoders can be challenged by spatially non-uniform sampling of image content. This is common in medical imaging, biology, and physics, where informative patterns occur rarely…
Local Attention Transformers for High-Detail Optical Flow Upsampling
Alexander Gielisse, Nergis Tömen, Jan van Gemert
Most recent works on optical flow use convex upsampling as the last step to obtain high-resolution flow. In this work, we show and discuss several issues and limitations of this cu…
HAVANA: Hierarchical stochastic neighbor embedding for Accelerated Video ANnotAtions
Alexandru Bobe, Jan C. van Gemert
Video annotation is a critical and time-consuming task in computer vision research and applications. This paper presents a novel annotation pipeline that uses pre-extracted feature…
Pushing the boundaries of event subsampling in event-based video classification using CNNs
Hesam Araghi, Jan van Gemert, Nergis Tomen
Event cameras offer low-power visual sensing capabilities ideal for edge-device applications. However, their high event rate, driven by high temporal details, can be restrictive in…
Aligning Object Detector Bounding Boxes with Human Preference
Ombretta Strafforello, Osman S. Kayhan, Oana Inel +2
Previous work shows that humans tend to prefer large bounding boxes over small bounding boxes with the same IoU. However, we show here that commonly used object detectors predict l…
