#123: Revamp general graph-based images -----------------------+---------------------------------------------------- Reporter: levill_r | Owner: levill_r Type: task | Status: assigned Priority: major | Milestone: Olena 1.0ß Component: Milena | Version: 1.0 Resolution: | Keywords: nbh neighb win -----------------------+---------------------------------------------------- Changes (by levill_r): * summary: Revamp general graph-based images (aka badly named « mesh images ») => Revamp general graph-based images Old description:
For starters, * ~~Use `graph` prefix instead of `mesh`~~ (done in r1704). * Improve the graph structure; possibly provide a BGL-based version of the graph-based image.
Then later: * Create a « add_neighborhood » morpher, and adjust window-based morpho algorithms so that they can work on images with neighborhoods (work started in r1686 and r1688, but far from being complete). [[BR]] See also #130. * Rename « mesh elementary window » as « graph elementary neighborhood » (or adjacency? Check formal definitions to choose the right term.). [[BR]] 2008-02-07: This needs more reflection; we probably need both (an elementary window ''and'' an elementary neighborhood for graphs). * Revamp this elementary neighborhood too (currently, the graph-based piters ignore them, and assume they always work on elementary neighborhoods).
These latest tasks might deserve their own ticket, as their scope is beyond graph-based images.
New description: For starters, * ~~Use `graph` prefix instead of `mesh`~~ (done in r1704). * ~~Improve the graph structure~~ (mostly done in r1713). * Possibly provide a BGL-based version of the graph-based image (IMHO, BGL graphs are much faster than ours, so this would make sense w.r.t. the efficiency point of view). Then later: * Create a « add_neighborhood » morpher, and adjust window-based morpho algorithms so that they can work on images with neighborhoods (work started in r1686 and r1688, but far from being complete).

These latest tasks might deserve their own ticket, as their scope is beyond graph-based images. Comment: Mention the fact that (undirected) graphs were overhauled in r1713. Update the title of the ticket. -- Ticket URL: <https://trac.lrde.org/olena/ticket/123#comment:4> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image processing library.
