Save image 25 or 26 and see if you can get anywhere near the processed

If you can map the aberrations in a satellite
lens system while it is still on earth and make
a transform from it, you can actually use an
inverse transform to remove the aberrations.
The result is a sharper image than the camera
actually saw.
No, it is just a _different_
That article may have been concerned with something I learned about at university
- inverse fourier transforms.
Right. It did involve fourier transforms of some sort (I
used to have some idea of what that means) but applied to
the image not the lens, if I am remembering right.

There are a few software packages designed to do just this for astronomical
images.. Lucy-Richardson Deconvolution, Maximum Entropy plus a couple more
algorithms.. very cpu intensive (forget about using a Pentium 200). I have not
been impressed by the results, too much work for an incremental

Yeah, that article has stuck in my mind also. I remember
that the method had to do with mathematically analyzing
circles of confusion to sharpen unsharp images (don't
remember anything about motion blur, but it might have been
there). I onced asked about it on some list or other and

I have to say this is a complete load of baloney. With one Levels setting,
e.g.:
input black 0
input gamma 2.5
input white 255
output black 0
output white 180
followed by USM:
Amount 200
Radius 200
followed by USM:
Amount 100
Radius 1
I can get something just like image 8 Retinexed, for

It definitely isn't rocket science we're seeing here.

This would work for satellite photos, in which the distance to the subject is
known and

I admit it is amazing what it does, especially in the saving of
images of
most other people could find images that could be
improved/rescued by a toned down version of this software.

A quick tip - DON'T try it on the previews, as I checked one of them (the fireman in
smoke haze), and it has not got any pixel variation in areas where the processed image
shows
