OK, I'm thinking of this problem sort of like that time I missed
an easy overhead and lost to that smart-aleck young kid and
came home and maybe pushed the door a little too hard with my
tennis bag and there was a bit of a hole in the dry wall.
"Thin Plate Spline" sounds like the wire gauze I had to
use to repair the darn thing. Is it like that?
If so, how could I use it to "repair" some dropped
data points in the center of my image, for example?
Cheers,
David
