SEMCITY TOULOUSE: A BENCHMARK FOR BUILDING INSTANCE SEGMENTATION IN SATELLITE IMAGES

Autor: R. Roscher, M. Volpi, C. Mallet, L. Drees, J. D. Wegner

Publikováno v: ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Vol V-5-2020, Pp 109-116 (2020)

In order to reach the goal of reliably solving Earth monitoring tasks, automated and efficient machine learning methods are necessary for large-scale scene analysis and interpretation. A typical bottleneck of supervised learning approaches is the ava

MULTI-MODAL DEEP LEARNING WITH SENTINEL-3 OBSERVATIONS FOR THE DETECTION OF OCEANIC INTERNAL WAVES

Autor: L. Drees, J. Kusche, R. Roscher

Publikováno v: ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Vol V-2-2020, Pp 813-820 (2020)

The observation of waves that propagate along density interfaces inside the ocean poses a significant challenge, as their visible surface signatures are much lower compared to their internal amplitudes. However, monitoring internal waves is important

ARCHETYPAL ANALYSIS FOR SPARSE REPRESENTATION-BASED HYPERSPECTRAL SUB-PIXEL QUANTIFICATION

Autor: L. Drees, R. Roscher

Publikováno v: ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Vol IV-1-W1, Pp 133-139 (2017)

This paper focuses on the quantification of land cover fractions in an urban area of Berlin, Germany, using simulated hyperspectral EnMAP data with a spatial resolution of 30m×30m. For this, sparse representation is applied, where each pixel with u

Photoinduced monooxygenation involving NAD(P)H-FAD sequential single-electron transfer

Autor: Simon Ernst, Stefano Rovida, Andrea Mattevi, Susanne Fetzner, Steffen L. Drees

Publikováno v: Nature Communications, Vol 11, Iss 1, Pp 1-11 (2020)

The number of usable light-responsive enzymes is limited, despite the potential biotechnological applications. Here, the authors report a flavoprotein monooxygenase which is controllable by blue light illumination, and propose a mechanism involving p

Substrate Inhibition of 5β-Δ4-3-Ketosteroid Dehydrogenase in Sphingobium sp. Strain Chol11 Acts as Circuit Breaker During Growth With Toxic Bile Salts

Autor: Franziska M. Feller, Gina Marke, Steffen L. Drees, Lars Wöhlbrand, Ralf Rabus, Bodo Philipp

Publikováno v: Frontiers in Microbiology, Vol 12 (2021)

In contrast to many steroid hormones and cholesterol, mammalian bile salts are 5β-steroids, which leads to a bent structure of the steroid core. Bile salts are surface-active steroids excreted into the environment in large amounts, where they are su
