Frost at the Viking 2 landing site (super-resolution)
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.
