Hello all
I have an IDL program that requires images to be moved by
very small amounts, often as little as one hundredth of a
pixel. Currently I am using a bilinear interpolation subroutine
that I wrote myself in IDL. I would like to upgrade to a
bicubic interpolator and am looking at the code in "Numerical
Recipes". It looks fairly straight forward but will take
some time to make it work effeciently.
So I thought I'd ask if anyone has a sub-pixel image movement
routine based on bicubic interpolation that they would be willing
to share.
Many thanks,
-Dyer
