Semantic-Aware Environment Perception for Mobile Human-Robot Interaction
Thorsten Hempel, Marc-André Fiedler, Aly Khalifa +2
Current technological advances open up new opportunities for bringing human-machine interaction to a new level of human-centered cooperation. In this context, a key issue is the se…
An Online Semantic Mapping System for Extending and Enhancing Visual SLAM
Thorsten Hempel, Ayoub Al-Hamadi
We present a real-time semantic mapping approach for mobile vision systems with a 2D to 3D object detection pipeline and rapid data association for generated landmarks. Besides the…
L2CS-Net: Fine-Grained Gaze Estimation in Unconstrained Environments
Ahmed A. Abdelrahman, Thorsten Hempel, Aly Khalifa +1
Human gaze is a crucial cue used in various applications such as human-robot interaction and virtual reality. Recently, convolution neural network (CNN) approaches have made notabl…
6D Rotation Representation For Unconstrained Head Pose Estimation
Thorsten Hempel, Ahmed A. Abdelrahman, Ayoub Al-Hamadi
In this paper, we present a method for unconstrained end-to-end head pose estimation. We address the problem of ambiguous rotation labels by introducing the rotation matrix formali…
