Abstract
In 2000, a geologist Fridtjof Riis discovered a meteor crater in Ritland, Hjelmelan
municipality in Rogland. This crater was formed by meteorite impact. The crater has
areas with a lot of cracks in the rocks, and geologists think these cracks are very
valuable information for them. By making photos with an ordinary camera, they want
to get binary pictures where the cracks are shown as white lines on a black
background. They can measure and quantify the length and direction of the cracks on
the binary image.
The objective of this project is to extract cracks from the digital photos. In this project,
statistical technique – linear regression, and image processing techniques like spatial
filtering, morphological operations have been used.
Binary images with white lines showing cracks on black background are generated as
result of this project. Geologists can use this result to analysis the cracks.
