The interacting multiple model filter and smoother on boxplus-manifolds

TL Koller, U Frese - Sensors, 2021 - mdpi.com
Hybrid systems are subject to multiple dynamic models, or so-called modes. To estimate the
state, the sequence of modes has to be estimated, which results in an exponential growth of …

Event-Domain Knowledge in Inertial Sensor Based State Estimation of Human Motion

TL Koller, T Laue, U Frese - 2022 25th International …, 2022 - ieeexplore.ieee.org
State estimation can significantly benefit from prior knowledge about a system's dynamics
and state. In this paper, we investigate a special class of prior knowledge: Events that …
