Hi,

I am thinking about estimating root length based on a
non-intersecting skeleton of a root scan.  The idea is to tally the
number of 4-connected and 8-connected (diagonals only) pixels, and
assign a length of 1 to each pair of 4-connected pixels and 1.414 to
each pair of 8-connected pixels.  Has someone already done this?  Or
is this a bad idea?

Thanks.
