You may have read on spaceweather about Einsteins famous eclipse photo has been restored:

The software used in part for this is called NAFE (Noise Adaptive Fuzzy Equalisation), it is used to process AIA data, handily spaceweather link to a paper about it here:

And at the bottom of the paper to the website where you can download it:

I downloaded and installed it and had a play, it's interesting, it certainly could be a useful tool in our solar image processing. I tried an image I took on 21st March, with quite poor quality raw data and was quite surprised:

It certainly adds a bit more texture to the image... I think it is something I will explore a bit more. Be interested to see other peoples findings...
