Changeset 20568 for trunk/ppStack/src/ppStackMatch.c

Message:

Adding parameter 'stride' to control the size of convolution patches (in pmSubtractionConvolve). Previously we have made this the (full) size of the kernel, but there's no reason why it can't be bigger. Making this value larger means the kernel doesn't have to be generated as often.
