Edge-detection applied to moving sand dunes on Mars
Amelia Carolina Sparavigna
TL;DR
This paper applies Sobel edge detection to compare Mars dune images from 1999 and 2007, enabling analysis of dune motion over a longer period than previous studies.
Contribution
It introduces the use of Sobel edge detection for analyzing dune movement on Mars, extending the temporal scope of such studies.
Findings
Detected dune motion between 1999 and 2007 images.
Demonstrated effectiveness of Sobel filter in planetary surface change analysis.
Extended the observation period for Martian dune dynamics.
Abstract
Here we discuss the application of an edge detection filter, the Sobel filter of GIMP, to the recently discovered motion of some sand dunes on Mars. The filter allows a good comparison of an image HiRISE of 2007 and an image of 1999 recorded by the Mars Global Surveyor of the dunes in the Nili Patera caldera, measuring therefore the motion of the dunes on a longer period of time than that previously investigated.
