Zhou, K. (author), Chen, Y. (author), Smal, I.V. (author), Lindenbergh, R.C. (author)Up-to-date 3D building models are important for many applications. Airborne very high resolution (VHR) images often acquired annually give an opportunity to create an up-to-date 3D model. Building segmentation is often the first and utmost step. Convolutional neural networks (CNNs) draw lots of attention in interpreting VHR images as they can...journal article 2019

Zhao, Junqiao (author), Ledoux, H. (author), Stoter, J.E. (author), Feng, Tiantian (author)The Level-of-Detail (LOD) 2 building models defined in CityGML are used widely in three-dimensional (3D) city applications. Many of these applications demand valid solid-based geometry (closed 2-manifold), which is crucial for analytical and computational purposes. However, this condition is often violated in practice because of the way LOD2...journal article 2018

Dominguez-Martin, B. (author), Van Oosterom, P. (author), Feito-Higueruela, F.R. (author), Garcia-Fernandez, A.L. (author), Ogayar-Anguita, C.J. (author)We present the preliminary results of a work in progress which aims to obtain a software system able to automatically generate a set of diverse 3D building models with a medium level of detail, that is, more detailed that a mere parallelepiped, but not as detailed as a complete geometric representation of the building. Each building model is...conference paper 2015
