We present a method for automatised detection and analysis of quasi-periodic lineament structures from images at pixel-precision. The method exploits properties of the images’ frequency domain found by using the Fourier transform. We developed this method with the goal of detecting lineament structures in an image of the Hathor cliff of comet 67P/C...

The Rosetta mission delivered images of comet 67P's nucleus at unprecedented resolution which indicate the presence of a global layering system. By merging techniques of structural geology, statistical image processing, and solar system science, this thesis aims to contribute to the understanding of the formation of the layerings, and thus of comet...

We are studying layering-related lineament structures on the nucleus surface of comet 67P/Churyumov-Gerasimenko ('67P') in order to determine the three-dimensional sub-surface orientation of its layerings. Our previously presented approach was limited to linear features with significant curvature, e.g. along hill slopes and the edges of mesas. This...

We analysed layering-related linear features on the surface of comet 67P/Churyumov-Gerasimenko (67P) to determine the internal configuration of the layerings within the nucleus. We used high-resolution images from the OSIRIS Narrow Angle Camera onboard the Rosetta spacecraft, projected onto the SHAP7 shape model of the nucleus, to map 171 layering-...

We studied the three-dimensional orientation of layerings in the nucleus of comet 67P/Churyumov-Gerasimenko ('67P'). Using high-resolution 2D images from the OSIRIS Camera system onboard the Rosetta spacecraft in combination with a 3D shape model of the nucleus, we mapped presumably layering-related linear features on the comet's surface, then appl...
