Terry,
I read the paper, and I don't think you'll be able to use your existing
images. The technique is based on first calibrating a lens to find
spatially varying point spread functions via a patch-based method and
then
using the known blur kernel to correct subsequent images. Without
properly
calibrated point spread functions, it won't work, and none of the
downloads
provide their calibration target or code to generate the point spread
functions. It also only corrects for blurs inherent in the lens optics,
not motion blurs.
I have a bit more of a think about this, and I am inclined to think that
the method may be applicable to the correction of any image, if one can
estimate the PSF.
If I understand it correctly, their approach is to derive, by test, a PSF
for the lens, then apply that PSF to correcting the image .
If one has other methods of deriving the PSF from the subject image (or
from a sharp and blurred pair as might be the case for pano work) then one
could use their method to apply that PSF to correcting the image.
A look in the "kernels" directory of the code package shows a kernel
"motion_blur.png" and some others that have the characteristics of motion
blur.
The above is a tad academic right now as the only means I have of testing
this is to use the code package with Octave.
As you have said, some of the Matlab functions that are used are not
available for Octave, and I'm not sure how I will go getting over that
hurdle.
Cheers,
