1737: Add a new test on WST-based segmentation on a line graph image.

by Roland Levillain

It seems ESIEE's mail server is preventing me from sending this message today. So I'm sending it by hand. Hope it won't look too much ugly, given the fact I'm sending it with Apple Mail (no troll intended). Hope ESIEE's mail server will return to a sound behavior soon, too... https://svn.lrde.epita.fr/svn/oln/trunk/milena Index: ChangeLog from Roland Levillain <roland(a)lrde.epita.fr> Add a new test on WST-based segmentation on a line graph image. * tests/core/lena_line_graph_image_wst.cc: Rename and move... * tests/morpho/lena_line_graph_image_wst1.cc: ...here.
