Event-based Semantic-aided Motion Segmentation

International audience ; Event cameras are emerging visual sensors inspired by biological systems. They capture intensity changes asynchronously with a temporal precision of up to µs, in contrast to traditional frame imaging techniques running at a fixed frequency of tens of Hz. However, effectively utilizing the data generated by these sensors requires the development of new algorithms and processing. In light of event cameras' significant advantages in capturing high-speed motion, researchers have turned their attention to event-based motion segmentation. Building upon (Mitrokhin et al., 2019) framework, we propose leveraging semantic segmentation enable the end-to-end network not only to segment moving objects from background motion, but also to achieve semantic segmentation of distinct moving objects. Remarkably, these capabilities are achieved while maintaining the network's low parameter count of 2.5M. To validate the effectiveness of our approach, we conduct experiments using the EVIMO dataset and the new and more challenging EVIMO2 dataset (Burner et al., 2022). The results demonstrate improvements attained by our method, showcasing its potential in event-based multi-objects motion segmentation.
