XNect: Real-time Multi-person 3D Human Pose Estimation with a Single RGB Camera

D. Mehta, O. Sotnychenko, F. Mueller, W. Xu, M. Elgharib, P. Fua, H.P. Seidel, H. Rhodin, G. Pons-Moll, C. Theobalt

A real-time multi-person 3D human body pose estimation system requiring only a single RGB camera for human motion capture in general scenes. The system produces full body 3D articulation estimates even under strong partial occlusion, as well as estimates of camera relative localization in space. The system can handle an arbitrary number of people in the scene, and processes complete frames without requiring prior person detection. A novel efficient convolutional network architecture (SelecSLS) enables real-time performance without compromising on accuracy. The pose formulation has the fully convolutional network only reason about the visible body parts, and occluded part reasoning is offloaded to a subsequent small fully connected network which gathers the full body context.

Convex Optimisation for Inverse Kinematics

T. Yenamandra, F. Bernard, J. Wang, F. Mueller, C. Theobalt

International Conference on 3D Vision (3DV) 2019

In this paper we propose a convex optimisation approach for the IK problem based on semidefinite programming, which admits a polynomial-time algorithm that globally solves (a relaxation of) the IK problem. Experimentally, we demonstrate that the proposed method significantly outperforms local optimisation methods using different real-world skeletons.

Real-time Pose and Shape Reconstruction of Two Interacting Hands With a Single Depth Camera

F. Mueller, M. Davis, F. Bernard, O. Sotnychenko, M. Verschoor, M. A. Otaduy, D. Casas, C. Theobalt

SIGGRAPH 2019

We present a novel method for real-time pose and shape reconstruction of two strongly interacting hands. Our approach is the first two-hand tracking solution that combines an extensive list of favorable properties, namely it is marker-less, uses a single consumer-level depth camera, runs in real time, handles inter- and intra-hand collisions, and automatically adjusts to the user's hand shape.

FingerInput: Capturing Expressive Single-Hand Thumb-to-Finger Microgestures for On-Skin Input

M. Soliman, F. Mueller, L. Hegemann, J. Sol Roo, C. Theobalt, J. Steimle

ACM International Conference on Interactive Surfaces and Spaces (ISS) 2018
Best Academic Paper Award

In this paper, we present a consolidated design space for thumb-to-finger microgestures. Based on this design space, we introduce a thumb-to-finger gesture recognition system which achieves an average accuracy of 91% for real-time detection of 8 demanding gesture classes.

International Conference on 3D Vision (3DV) 2018

A single-shot approach to jointly predict 3D body pose of multiple subjects in general scenes without requiring prior bounding-box extraction. Trained on new composited MuCo-3DHP dataset and evaluated on a new recorded multi-person 3D pose benchmark MuPoTS-3DHP.

GANerated Hands for Real-Time 3D Hand Tracking from Monocular RGB

F. Mueller, F. Bernard, O. Sotnychenko, D. Mehta, S. Sridhar, D. Casas, C. Theobalt

Spotlight @ Computer Vision and Pattern Recognition (CVPR) 2018

We propose a novel method for real-time hand tracking from monocular RGB input which combines a CNN-based regressor and a kinematic optimization framework. To enhance our synthetic training data, we introduce a new geometrically consistent image-to-image translator for unpaired examples.

Real-time Hand Tracking under Occlusion from an Egocentric RGB-D Sensor

F. Mueller, D. Mehta, O. Sotnychenko, S. Sridhar, D. Casas, C. Theobalt

International Conference on Computer Vision (ICCV) 2017

We present a method for real-time hand tracking under occlusion in cluttered egocentric scenes from a single RGB-D camera. To enable training of our machine learning components, we introduce a new large-scale dataset SynthHands which was captured using a mixed reality approach. Furthermore, we propose a real benchmark dataset EgoDexter which provides annotated fingertip positions.
