https://svn.lrde.epita.fr/svn/oln/trunk/milena Index: ChangeLog from Thierry Geraud <thierry.geraud@lrde.epita.fr> Add activity to morphology algebraic canvas. * mln/canvas/morpho/algebraic_union_find.hh (activity): New. This allows for accumulators that cannot properly implement set_value to work with algebraic filters and levelings. * mln/test/predicate.hh: Fix signature. canvas/morpho/algebraic_union_find.hh | 10 +++++++++- test/predicate.hh | 12 ++++++------ 2 files changed, 15 insertions(+), 7 deletions(-) Index: mln/test/predicate.hh --- mln/test/predicate.hh (revision 3174) +++ mln/test/predicate.hh (working copy) @@ -1,4 +1,5 @@ -// Copyright (C) 2007 EPITA Research and Development Laboratory +// Copyright (C) 2007, 2008 EPITA Research and Development Laboratory +// (LRDE) // // This file is part of the Olena Library.
