Paper accepted at CVPR 2020

Our paper with the title “HandVoxNet: Deep Voxel-Based Network for 3D Hand Shape and Pose Estimation from a Single Depth Map” has been accepted for publication at the IEEE/CVF Conference on Computer Vision and Pattern Recognition 2020 (CVPR 2020) which will take place from June 14th to 19th, 2020 in Seattle, Washington, USA. It is the “premier” conference in the field of Computer Vision. Our paper was accepted from 6656 submissions as one of 1470 (acceptance rate: 22 %).

Abstract: We propose a novel architecture with 3D convolutions for simultaneous 3D hand shape and pose estimation trained in a weakly-supervised manner. The input to our architecture is a 3D voxelized depth map. For shape estimation, our architecture produces two different hand shape representations. The first is the 3D voxelized grid of the shape which is accurate but does not preserve the mesh topology and the number of mesh vertices. The second representation is the 3D hand surface which is less accurate but does not suffer from the limitations of the first representation. To combine the advantages of these two representations, we register the hand surface to the voxelized hand shape. In extensive experiments, the proposed approach improves over the state-of-the-art for hand shape estimation on the SynHand5M dataset by 47.8%. Moreover, our 3D data augmentation on voxelized depth maps allows to further improve the accuracy of 3D hand pose estimation on real datasets. Our method produces visually more reasonable and realistic hand shapes of NYU and BigHand2.2M datasets compared to the existing approaches.

Paper published in IJCV

The International Journal of Computer Vision (IJCV) is considered one of the top journals in Computer Vision. It details the science and engineering of this rapidly growing field. Regular articles present major technical advances of broad general interest. Survey articles offer critical reviews of the state of the art and/or tutorial presentations of pertinent topics.

We are proud to announce that our paper “SceneFlowFields++: Multi-frame Matching, Visibility Prediction, and Robust Interpolation for Scene Flow Estimation” has been published in the IJCV (for more information click here). It is an extension of our earlier WACV paper “SceneFlowFields: Dense Interpolation of Sparse Scene Flow Correspondences“.

IFA 2019: Intelligent sensor technology for a better posture at the workplace

At the Internationale Funkausstellung (IFA 2019) – the world’s leading trade fair for consumer electronics and home appliances – at the beginning of September in Berlin, researchers from the TU Kaiserslautern (TUK) and the DFKI research area Augmented Reality presented a sensor system that reduces incorrect posture at the workplace. Sensors are used which are attached to different parts of the body such as the arms, spine and legs and which determine the movement sequences. Software evaluates the data and calculates movement parameters such as joint angles on the arm and knee or the degree of flexion or twisting of the spine. The system immediately detects if a movement is carried out incorrectly or if an incorrect posture is adopted. Via a Smartwatch, the system gives the user direct feedback so that he can correct movement or posture. The sensors could be integrated into work clothing and shoes. The run at the IFA was great and the project prototype was assessed very positively throughout. The press was also represented in large numbers.  Please find the links to the articles below.

Kick-Off meeting of the EU project HyperCOG

Dr. Alain Pagani, and Mohamed Selim (Augmented Vision department) and Ludgar Van Elst (Smart Data and Services department) participated in the Kick-off meeting of the EU project HyperCOG on September 24th, 2019, that was held at IK4-LORTEK in Spain.

HyperCOG project “HYPERCONNECTED ARCHITECTURE FOR HIGH COGNITIVE PRODUCTION PLANTS” addresses the full digital transformation of the process industry and cognitive process production plants through an innovative Industrial Cyber-Physical System (ICPS). It is based on commercially available advanced technologies that will enable the development of a hyper-connected network of digital nodes. The nodes can catch outstanding streams of data in real-time, which together with the high computing capabilities available nowadays, provide sensing, knowledge and cognitive reasoning to the industrial business. The project will strive to demonstrate how data technologies embedded in a CPS platform applied in the process industry can streamline processes, achieve a step gain in efficiency, sustainability and resource utilization and act as a basis for the provision of new services.

In HyperCOG, 14 international partners have joined forces, bringing together the necessary competence in terms of expertise and resources to ensure the achievement of the project goals. In DFKI, the departments “Augmented Vision” and the department “Smart Data and Services” at DFKI Kaiserslautern are involved.

The Augmented Vision department is responsible for developing smart sensing technologies based on visual perception and visual interpretation for different use cases in active industrial plants. Moreover, in industrial plants, with a growing amount of sensors and data, the information load might increase and hinder the monitoring task. Augmented Vision department will carry out the work on AR to present contextualized information in a simple and direct way.
