An evaluation of Deep Learning based stereo dense matching dataset shift from aerial images and a large scale stereo dataset

1 code implementation19 Feb 2024 Teng Wu, Bruno Vallet, Marc Pierrot-Deseilligny, Ewelina Rupnik

To address this challenge, we propose a method for generating ground-truth disparity maps directly from Light Detection and Ranging (LiDAR) and images to produce a large and diverse dataset for six aerial datasets across four different areas and two areas with different resolution images.

SparseSat-NeRF: Dense Depth Supervised Neural Radiance Fields for Sparse Satellite Images

1 code implementation1 Sep 2023 Lulin Zhang, Ewelina Rupnik

However, NeRF and its variants require many views to produce convincing scene's geometries which in earth observation satellite imaging is rare.

DeepSim-Nets: Deep Similarity Networks for Stereo Image Matching

1 code implementation17 Apr 2023 Mohamed Ali Chebbi, Ewelina Rupnik, Marc Pierrot-Deseilligny, Paul Lopes

Our features are learnt on large image tiles to be expressive and capture the scene's wider context.

Pointless Global Bundle Adjustment With Relative Motions Hessians

1 code implementation11 Apr 2023 Ewelina Rupnik, Marc Pierrot-Deseilligny

Bundle adjustment (BA) is the standard way to optimise camera poses and to produce sparse representations of a scene.

A pipeline for automated processing of Corona KH-4 (1962-1972) stereo imagery

no code implementations19 Jan 2022 Sajid Ghuffar, Tobias Bolch, Ewelina Rupnik, Atanu Bhattacharya

The Corona KH-4 reconnaissance satellite missions from 1962-1972 acquired panoramic stereo imagery with high spatial resolution of 1. 8-7. 5 m. The potential of 800, 000+ declassified Corona images has not been leveraged due to the complexities arising from handling of panoramic imaging geometry, film distortions and limited availability of the metadata required for georeferencing of the Corona imagery.

Feature matching for multi-epoch historical aerial images

no code implementations8 Dec 2021 Lulin Zhang, Ewelina Rupnik, Marc Pierrot-Deseilligny

The method consists of: (1) an inter-epoch DSMs matching to roughly co-register the orientations and DSMs (i. e, the 3D Helmert transformation), followed by (2) a precise inter-epoch feature matching using the original RGB images.
