We propose AT-GS, a novel method for reconstructing high-quality dynamic surfaces from multi-view videos through per-frame incremental optimization. To avoid local minima across frames, we introduce a unified and adaptive gradient-aware...

This paper presents an automated drywall analysis method for construction progress and quality assessment using on-site cameras. It integrates a deep learning-based segmentation model to detect and classify drywall elements, with a module to...

NeRFs struggle with low-textured areas, causing "floaters" that reduce realism, especially on featureless surfaces. We propose a method for computing dense depth priors for these areas, using a novel depth loss function and patch regularization...

We demonstrate blind 6x6 adaptive equalization of 32 GBd DP-QPSK 3-mode transmission over a 54 km FMF based on the singularity-free convergence ability of the correlation-avoidance CMA (CA-CMA). The CA-CMA is used for robust pre-convergence in a...

We report on a wide-beam LiFi transmitter using multiple VCSEL arrays with digital drivers. We transmit a 3.75 GBd PAM-3 signal at a gross data rate of 5.625 Gbit/s. Single-driver OOK operation yields 7.75 GBd.

We propose a novel solution using the Eclipse Dataspace Components (EDC) Connector to enable regulated and policy-driven telemetry data sharing in telco ecosystems. We present its architecture, several compatible use-cases, and results validating...

Despite extensive theoretical progress in reconfigurable intelligent surfaces (RISs), practical models and network-level studies remain limited. This paper bridges the gap, exploring RIS-assisted links, proposing a control plane approach, and...

This paper compares different raytracing tools in the sub-THz area, to analyze the weight of several different effects, e.g. reflections, diffractions, scattering or atmospheric attenuation, during raytracing simulations for high frequencies. For...

Researchers from Deutsche Telekom AG and Fraunhofer HHI explores the Link Tomography, a receiver-based DSP approach for monitoring optical networks and detecting anomalies. Delving into concepts and building methodologies, it addresses challenges...

In this work, we introduce concepts for spatially resolved magnetic field sensing and two-dimensional gradiometry with an integrated magnetic field camera. The camera utilizes infrared absorption optically detected magnetic resonance (IRA ODMR)...
