[ptx] dirty lens and autopano-sift?

[manouchk]

Hi,

I would like to know if you know what I could do to improve results of 
autopano-sift in the case of very dirty lens (old microscope) and that I'm 
willing to stitch "big" set of photos using autopano-sift.

Can look at the "type" photos I'm trying to stitch there :

Lens is so dirty that it leads to very annoying that autopanosift ends using 
as stitching points on photos that doesn't share area the one with the other. 
Does anyone have an idea of a software that allow to remove those type of 
artifacts ?? (maybe I should have shooted a "flat" photo to use it as a 
reference?)

Trying autopanosift I remark that autopanosift almost didn't found any 
"remarquable" stitching points (angles...). Is it a limitation of sift 
algorithm does not detect this type of point ?

I'm doing it by hand without autopano-sift! Any ideas/suggestions are welcome.

Cheers,
EMmanuel
