Frost at the Viking 2 landing site (super-resolution)
Filed under pretty pictures, amateur image processing, Mars, NASA Mars missions before 1996, weather and climate
This image of frost on Mars has become iconic.� Unfortunately, it is tiny, because it was obtained using Viking's low resolution mode and there was no high resolution image taken along with it. This version of the image was processed using a super-resolution technique.

Using a different high resolution image and simply using the color as an overlay would not work, because the frost would be absent or the patterns wouldn't match.� Other image sets of the frost exist, but they have more serious problems with over/under exposure due to the high contrast of the scene and the limitations of the Viking imaging system. Therefore, I used super-resolution processing, a technique pioneered by Tim Parker of JPL, in order to get the best resolution I could out of the existing dataset.� The result is quite pleasing.�
