applying poly_2d to larger images [message #943]

Hi,

If I want to correct an image for some distortions I
apply POLY_WARP and POLY_2d (Wave). No problem.

But when handling larger images this approach fails for
not enough memory.

So my question is:
Has anybody out there ever tried to apply those functions
to larger images (maybe in blocks, or in an anchor-point-
approach)?

(I've tried to work with blocks of all columns and n blocks,
but succeeded just for polynomials with degree=1.)
