Changeset 14329 for trunk/psModules/src/imcombine/pmSubtraction.c

Timestamp:

Jul 19, 2007, 3:53:41 PM (19 years ago)

Author:

Paul Price

Message:

Not using psPolynomials to do spatial polynomials --- it's awkward,
confusing (x,y or y,x?) and I'm afraid the way it behaves will get
changed underneath me.
Adding function to generate image of each of the components of the
solution kernel.
Ensuring entire image gets convolved.
