[Olena-patches] cleanup-2008 2872: Make morpho erosion generic impl rely on accu transform.

https://svn.lrde.epita.fr/svn/oln/branches/cleanup-2008/milena Index: ChangeLog from Thierry Geraud &lt;thierry.geraud(a)lrde.epita.fr&gt; Make morpho erosion generic impl rely on accu transform. * mln/set/compute.hh (todo): New. * mln/morpho/erosion.hh (erosion_on_function): Rely on accu transform. * mln/morpho/erosion.spe.hh (erosion_on_function_fastest) Remove; useless since accu::transform is specialized for fastest input. (dispatch for the generic version): Remove; useless. morpho/erosion.hh | 21 +++--------------- morpho/erosion.spe.hh | 58 -------------------------------------------------- set/compute.hh | 5 +++- 3 files changed, 8 insertions(+), 76 deletions(-) Index: mln/set/compute.hh --- mln/set/compute.hh (revision 2871) +++ mln/set/compute.hh (working copy) @@ -30,9 +30,12 @@ /// \file mln/set/compute.hh /// -/// Compute an accumulator on a site set. +/// Compute an accumulator on a site set or a binary image. +/// +/// \todo Add a version with a binary image as input. # include <mln/core/concept/meta_accumulator.hh> +# include <mln/core/concept/image.hh> # include <mln/core/concept/site_set.hh> Index: mln/morpho/erosion.spe.hh --- mln/morpho/erosion.spe.hh (revision 2871) +++ mln/morpho/erosion.spe.hh (working copy) @@ -97,38 +97,6 @@ template <typename I, typename W> mln_concrete(I) - erosion_on_function_fastest(const Image<I>& input_, const Window<W>& win_) - { - trace::entering("morpho::impl::erosion_on_function_fastest"); - - typedef mln_concrete(I) O; - const I& input = exact(input_); - const W& win = exact(win_); - - extension::adjust_fill(input, win, mln_max(mln_value(I))); - - O output; - initialize(output, input); - - mln_pixter(const I) p(input); - mln_pixter(O) o(output); - mln_qixter(const I, W) q(p, win); - accu::min<mln_value(I)> min; - for_all_2(p, o) - { - min.init(); - for_all(q) - min.take(q.val()); - o.val() = min.to_result(); - } - - trace::exiting("morpho::impl::erosion_on_function_fastest"); - - return output; - } - - template <typename I, typename W> - mln_concrete(I) erosion_on_set_fastest(const Image<I>& input_, const Window<W>& win_) { trace::entering("morpho::impl::erosion_on_set_fastest"); @@ -1169,32 +1137,6 @@ namespace internal { - // dispatch for the generic version - - // FIXME: De-activate because when the window is multiple, the access - // win.dp(i), used in dpoints_pixter, is impossible. - - // template <typename I, typename W> - // mln_concrete(I) - // erosion_dispatch_for_generic(trait::image::kind::logic, // On sets. - // trait::image::speed::fastest, - // const I& input, const W& win) - // { - // if (win.is_centered()) - // return impl::erosion_on_set_centered_fastest(input, win); - // else - // return impl::erosion_on_set_fastest(input, win); - // } - - // template <typename I, typename W> - // mln_concrete(I) - // erosion_dispatch_for_generic(trait::image::kind::any, // On functions. - // trait::image::speed::fastest, - // const I& input, const W& win) - // { - // return impl::erosion_on_function_fastest(input, win); - // } - template <typename I, typename W> mln_concrete(I) erosion_dispatch_for_generic(trait::image::kind::logic, // On sets.
