Re:PolyWorld - A Graph Neural Network for Polygonal Scene Parsing

no code implementations ICCV 2023 Stefano Zorzi, Friedrich Fraundorfer

Re:PolyWorld not only outperforms the original model on building extraction in aerial images, thanks to the proposed joint analysis of vertices and edges, but also beats the state-of-the-art in multiple other domains.

PolyWorld: Polygonal Building Extraction with Graph Neural Networks in Satellite Images

1 code implementation CVPR 2022 Stefano Zorzi, Shabab Bazrafkan, Stefan Habenschuss, Friedrich Fraundorfer

While most state-of-the-art instance segmentation methods produce binary segmentation masks, geographic and cartographic applications typically require precise vector polygons of extracted objects instead of rasterized output.

Map-Repair: Deep Cadastre Maps Alignment and Temporal Inconsistencies Fix in Satellite Images

no code implementations24 Jul 2020 Stefano Zorzi, Ksenia Bittner, Friedrich Fraundorfer

In the fast developing countries it is hard to trace new buildings construction or old structures destruction and, as a result, to keep the up-to-date cadastre maps.

Regularization of Building Boundaries in Satellite Images using Adversarial and Regularized Losses

no code implementations23 Jul 2020 Stefano Zorzi, Friedrich Fraundorfer

In this paper we present a method for building boundary refinement and regularization in satellite images using a fully convolutional neural network trained with a combination of adversarial and regularized losses.
