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

Absolutely awesome work you two. I would love to see NASA show your images, as an example of the "Citizen Science" they are encouraging and promoting so hard.

Here is an off the wall idea to get better focused images using the MI while peeking under Spirit's deck.
The rough idea is to increase the speed of the exposure, a well known technique to increase depth of field < i don't know if that is possible > Another, is to decrease the aperture size, which increases the f number < i dont know if that is possible > BUT ! If you cant do either of those , then decrease the amount of light per exposure, by timing the shot at dusk or dawn, and by taking multiple shots with the waning (or gathering) light. By using enhancement tools (and much more limited deconvolution), the JPL team may gain the insight they require for the sandbox simulations. <??> ..,Spirit has a ton of watts and time.... <...well it seemed like a good idea while I was stuck in traffic...> -------------------- CLA CLL

Do you mean to make the exposure time shorter? QUOTE ...

I'm not sure how decreasing light and/or exposure time would yeld a better image. Can you point me to some place that describes these image processing algorithms?
