ModSelect: Automatic Modality Selection for Synthetic-to-Real Domain Generalization

no code implementations19 Aug 2022 Zdravko Marinov, Alina Roitberg, David Schneider, Rainer Stiefelhagen

Modality selection is an important step when designing multimodal systems, especially in the case of cross-domain activity recognition as certain modalities are more robust to domain shift than others.

Multimodal Generation of Novel Action Appearances for Synthetic-to-Real Recognition of Activities of Daily Living

1 code implementation3 Aug 2022 Zdravko Marinov, David Schneider, Alina Roitberg, Rainer Stiefelhagen

We tackle this challenge and introduce an activity domain generation framework which creates novel ADL appearances (novel domains) from different existing activity modalities (source domains) inferred from video training data.

A Comparative Analysis of Decision-Level Fusion for Multimodal Driver Behaviour Understanding

no code implementations10 Apr 2022 Alina Roitberg, Kunyu Peng, Zdravko Marinov, Constantin Seibold, David Schneider, Rainer Stiefelhagen

Visual recognition inside the vehicle cabin leads to safer driving and more intuitive human-vehicle interaction but such systems face substantial obstacles as they need to capture different granularities of driver behaviour while dealing with highly limited body visibility and changing illumination.
