Guys, this is what I mentioned on the list last night.
I think this is the reason Yiwen is not getting perfect results with the oracle masks.
On this line, you need to negate the offsets. If you want the current pixel to contain the reference at this pixel plus the offset, you need to roll the image with the negative of the offset.
