Hi,

Here is a try to super resolution imaging, by using Iris, a software made for astronomical imagery processing.

I took the Sol 984 images and stack and align them to have a better resolution.

Before, I resised all the frames at 200%.

One of the 15 originals raw images :


And the final picture :


The result is a little visible, but, to have better resolution, I need more than 15 pictures (in astronomical processing, we need a thousand pictures extract from an avi film).

Realistically, you need to be using the uncompressed data - not raw JPG's complete with compression artifacts.

The analogy with planetary imaging with a webcam doesn't hold too well. The reason one takes hundreds of images is because within those hundreds there will be perhaps a dozen frames of near perfect 'seing' where just for a moment the column mass of air was not screwing the image quite so much.

With surface-to-surface imaging such as these super-res sequences, that's not the case - every frame you aquire is a 'good' one so you don't need hundreds of images.

What might be interesting is to compare one of these sequences ( given that the early Olympia outcrop super reses from the early 700's is on the PDS now ) - and try it with the JPG's - the RAD's and then compare to the Pancam teams efforts - http://pancam.astro.cornell.edu/pancam_ins...t/superres.html
