Due to the COVID-19 pandemic, smartphone-based proximity tracing systems became of utmost interest. Many of these systems use Bluetooth Low Energy (BLE) signal strength data to estimate the distance between two persons. The quality of this method depends on many factors and, therefore, does hardly deliver accurate results. We present a multi-channel approach to improve proximity classification, and a novel, publicly available data set that contains matched ieee 802.11 (2.4 & 5 GHz) and BLE signal strength data, measured in four different environments. We utilize these data to train machine learning models. The evaluation showed significant improvements in the distance classification and consequently also the contact tracing accuracy. However, we also encountered privacy problems and limitations due to the consistency and interval at which such probes are sent. We discuss these limitations and sketch how our approach could be improved to make it suitable for real-world deployment.

Road crack segmentation plays a pivotal role in infrastructure maintenance, ensuring the safety and longevity of road networks. This study presents a meticulous investigation into the efficacy of various U-Net variants and contemporary models for road crack segmentation using a well-annotated dataset. In this study, we evaluated the performance of ResU-Net++, U-Net, U-Net++, U-Net3+, TransResU-Net, DeepLabV3+, Polyp-PVT, and PraNet. Notably, Poly-PVT exhibited remarkable performance, achieving a Jaccard index of 0.5648 and an F1-score of 0.7063, signifying superior crack segmentation capabilities. Furthermore, TransResU-Net's comparatively lower metrics indicate potential feature overcomplication for this dataset. The findings suggest that Poly-PVT with its full-scale multi-level feature fusion excels in capturing both local nuances and global context, solidifying its position as an effective model for road crack segmentation. This comprehensive evaluation contributes valuable insights to the field, aiding researchers and practitioners in selecting the most suitable model for this critical infrastructure maintenance task.

Single-view 3D reconstruction has long been an intractable and fundamental problem in computer vision. Objects with complex topological structures are difficult to be accurately reconstructed, which makes the existing methods suffer from blurred shape boundaries between multiple components in the object. Recently, convolutional neural network and vision transformer have begun to appear in the field of 3D reconstruction and have been widely used with excellent performance. However, the existing transformer-based methods mainly focus on the global long-term context dependency, and ignore the local details of the part space features, resulting in poor reconstruction of the detail part. In this paper, we propose a novel dual-branch network architecture, called IFA-Net, to capture local spatial perception information and retain global structural features for singleview 3D reconstruction. In addition, we propose an isomerous feature-aware module, which enables the dynamic fusion of different resolution features under the two branches. Thus, high-fidelity and detail-rich 3D object reconstruction can be achieved. Extensive experimental results demonstrate that our method is able to produce high-quality voxels, particularly with diverse topologies, as compared with the state-of-the-art methods.
