10.2018: Our interdisciplinary paper on pupil-based assesment of human cognitive load using Bayesian methods was presented at the ACM ICMI Modeling Cognitive Processes from Multimodal Data Workshop (ICMI-MCPMD).

08.2018:   Two papers accepted at BMVC and ECCV Workshop! One paper about identifying previously unseen classes for action recognition in open-set scenario is accepted at the BMVC and one paper on assessing the performance of zero-shot action recognition algorithms when using external datasets was accepted at the ECCV Workshop on Shortcomings in Vision and Language.

07.2018:   I participated in the International Computer Vision Summer School and presented our poster "Human Activity Recognition in Autonomous Vehicles"

Research Interests

My main research focus is deep learning-based recognition of human activities and interactions from video streams. I am especially interested in open-set, zero- and few-shot recognition as well as applying the developed models for driver monitoring in intelligent vehicles.

I am involved in the BMBF Project PAKoS (Personalisierte, adaptive kooperative Systeme für automatisierte Fahrzeuge), working on scene understanding inside autonomous cars. The goal of CV:HCI is real-time activity recognition under realistic driving conditions (e.g. varying or low illumination).
