What Streets of Boston said.
And if your filters need some amount of neighbouring pixels, you may be
able to use overlapping slices, provided you're real careful with how
you do the calculations in the overlapping parts.

not, as I saw suggested in one of the many old posts I read, reducing
the resolution to work with it, and then raising it back up to full
resolution, presumably thinking that the lost resolution would just
magically restore itself.:-)
Um, I don't think such magic exists. Not in computers, anyway :)
