Uncertainty Estimation in Instance Segmentation with Star-convex Shapes

no code implementations19 Sep 2023 Qasim M. K. Siddiqui, Sebastian Starke, Peter Steinbach

Two distinct clustering approaches are evaluated which compute spatial and fractional certainty per instance employing samples by the Monte-Carlo Dropout or Deep Ensemble technique.

Motion In-Betweening with Phase Manifolds

1 code implementation24 Aug 2023 Paul Starke, Sebastian Starke, Taku Komura, Frank Steinicke

This paper introduces a novel data-driven motion in-betweening system to reach target poses of characters by making use of phases variables learned by a Periodic Autoencoder.

QuestEnvSim: Environment-Aware Simulated Motion Tracking from Sparse Sensors

no code implementations9 Jun 2023 Sunmin Lee, Sebastian Starke, Yuting Ye, Jungdam Won, Alexander Winkler

Most existing methods for motion tracking avoid environment interaction apart from foot-floor contact due to their complex dynamics and hard constraints.

Avatars Grow Legs: Generating Smooth Human Motion from Sparse Tracking Inputs with Diffusion Model

1 code implementation CVPR 2023 Yuming Du, Robin Kips, Albert Pumarola, Sebastian Starke, Ali Thabet, Artsiom Sanakoyeu

A particular challenge is that only a sparse tracking signal is available from standalone HMDs (Head Mounted Devices), often limited to tracking the user's head and wrists.

PhaseMP: Robust 3D Pose Estimation via Phase-conditioned Human Motion Prior

no code implementations ICCV 2023 Mingyi Shi, Sebastian Starke, Yuting Ye, Taku Komura, Jungdam Won

We present a novel motion prior, called PhaseMP, modeling a probability distribution on pose transitions conditioned by a frequency domain feature extracted from a periodic autoencoder.
