Multi-task Learning for Human Settlement Extent Regression and Local Climate Zone Classification

no code implementations23 Nov 2020 Chunping Qiu, Lukas Liebel, Lloyd H. Hughes, Michael Schmitt, Marco Körner, Xiao Xiang Zhu

Human Settlement Extent (HSE) and Local Climate Zone (LCZ) maps are both essential sources, e. g., for sustainable urban development and Urban Heat Island (UHI) studies.

A Generalized Multi-Task Learning Approach to Stereo DSM Filtering in Urban Areas

no code implementations6 Apr 2020 Lukas Liebel, Ksenia Bittner, Marco Körner

Such basic models can be filtered by convolutional neural networks (CNNs), trained on labels derived from digital elevation models (DEMs) and 3D city models, in order to obtain a refined DSM.
