Here is a work in progress.
I was working on a another thread (processing the envelope challenge for PFK) and thought I could use the same technique to 'see' underneath Spirit's deck with the MI. While I don't fix the focus, the technique does what amounts to a smart contrast... If anyone would like to to do a mosaic, i would appreciate it (I haven't done them enough to pull them off like you guys) I will post the whole underbelly later, but here are the test images: Cheers and thanks! -------------------- CLA CLL

For those who intend to do serious work on attacking the defocus, here are two documents which may come in useful, as they describe the technical and lens specifications for the Microscopic Imager. The toughest part is likely computing the proper PSF for each individual point on the image, as that would require knowledge of the exact distance to each pixel, which requires photogrammetric calculations that usually require a sharp stereo pair! The anaglyph may help, but an accurate mesh of the surroundings is somewhat of a goal and not available for input...one (crazy) option is an iterative bundle adjustment that starts with a good estimate for some sort of photometric textured mesh model for the situation and improves its estimate by repeatedly raytracing this model into images based on the camera parameters and checking how well they correspond to reality? Yes, I know this would probably require a couple supercomputers' worth of processing power and whatnot, but it might be worth a try...
