scanned images). The mentioned d and e parameters for the D70 where
the result when creating a batch stitching template in a room paved
with post-it stickers. 1514 control points where evenly distributed
throughout all overlaps and of course I looked here more for the
stitching and less for the pixel error (although the pixel error *is*
a measure if you have enough well distributed points and you
repeatedly optimize and use APCLean)...
