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

This is something I did a few weeks ago using the DeconBL (Biggs-Lucy Iterative Blind Deconvolution) routine in P.J. Tadrous's excellent Biaram suite of command-line image processing tools (bialith.com) for 8,192 iterations of alternating PSF and image estimation steps. The animated GIF is composed of the output at N=0, 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 4096, and 8192 iterations. Unfortunately, after about 2000 iterations, the process began converging to what is essentially just a noisy version of the original image. However, some of the images in between may be useful. The entire process took over 100 CPU hours, but could be repeated more efficiently for the other images by stopping after the 1024th iteration.
EDIT: whoops I ran out of bandwidth on the first site I was hosting that image at... ADMIN: Large embedded file replaced with smaller version of animation above. Original 10mb version available here. |
