Automated crater detection with human level performance
Lee, Christopher; Hogan, James
Crater cataloging is an important yet time-consuming part of geological mapping. We present an automated Crater Detection Algorithm (CDA) that is competitive with expert-human researchers and hundreds of times faster.
The CDA uses multiple neural networks to process digital terrain model and thermal infra-red imagery to identify and locate cr…A progressive black top hat transformation algorithm for estimating valley volumes on Mars
Luo, Wei; Jung, Jaehoon; Pingel, Thomas +2 more
The depth of valley incision and valley volume are important parameters in understanding the geologic history of early Mars, because they are related to the amount sediments eroded and the quantity of water needed to create the valley networks (VNs). With readily available digital elevation model (DEM) data, the Black Top Hat (BTH) transformation,…
Tectonic lineament mapping of the Thaumasia Plateau, Mars: Comparing results from photointerpretation and a semi-automatic approach
Di Achille, Gaetano; Vaz, David A.; Barata, Maria Teresa +1 more
Photointerpretation is the technique generally used to map and analyze the tectonic features existent on Mars surface. In this study we compare qualitatively and quantitatively two tectonic maps based on the interpretation of satellite imagery and a map derived semi-automatically. The comparison of the two photointerpreted datasets allowed us to i…
Implementation of Martian virtual reality environment using very high-resolution stereo topographic data
Kim, Jung-Rack; Lin, Shih-Yuan; Hong, Jeong-Woo +2 more
Topography over terrestrial or other planetary surfaces is an important base data for virtual reality construction. In particular, with inaccessible topography such as the Martian surface, virtual reality provides great value not only for public interaction but also for scientific research. For the latter application, since field surveys are essen…
Coregistration of Mars Orbiter Laser Altimeter (MOLA) topography with high-resolution Mars images
Kolb, Kelly J.; Okubo, Chris H.
Spacecraft continue to send back extraordinary amounts of data from Mars leaving scientists with the considerable task of analyzing an ever-increasing wealth of information. There are abundant uses for coregistered topography and images, but coregistering various datasets can be time-consuming and labor-intensive. We have developed a set of C-shel…
MIMS—A relational database of imagery on Mars
Vaz, D.; Alves, E. Ivo
Mars Image Mining System (MIMS) is a relational database of internet links to most of the images which were acquired by missions Mariner 9, Viking 1 and 2, Mars Global Surveyor, Mars Odyssey and Mars Express (a total of 329,240 images on December 15, 2005). Unlike existing online databases, it allows to search for images of several missions simult…
