[Olena] #130: Don not pass neighborhoods as argument to algorithms

by Olena

#130: Don not pass neighborhoods as argument to algorithms ----------------------+----------------------------------------------------- Reporter: levill_r | Owner: Olena Team Type: defect | Status: new Priority: major | Milestone: Olena 1.0ß Component: Milena | Version: 1.0 Keywords: | ----------------------+----------------------------------------------------- Neighborhoods shall be bound to images: they are a property of them. Hence an algorithm (at least a facade) shall not accept an image along with an ''external'' neighborhood. Most of the time, these algorithms are based on windows improperly called neighborhoods. Here is the list of files to revamp, as of revision 1663: * source:trunk/labeling/level.spe.hh * source:trunk/labeling/regional_maxima.hh * source:trunk/labeling/regional_minima.hh * source:trunk/make/voronoi.hh * source:trunk/milena/mln/geom/labeling/blobs.hh * source:trunk/milena/mln/geom/seeds2tiling_roundness.hh * source:trunk/milena/mln/labeling/background.hh * source:trunk/milena/mln/labeling/flat_zones.hh * source:trunk/milena/mln/labeling/foreground.hh * source:trunk/milena/mln/labeling/level.hh * source:trunk/morpho/Rd.hh * source:trunk/morpho/dilation.hh * source:trunk/morpho/opening_area.hh * source:trunk/morpho/opening_attribute.hh -- Ticket URL: <https://trac.lrde.org/olena/ticket/130> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image library.

[Olena] #127: Generalize the definition of the Sobel gradient

#127: Generalize the definition of the Sobel gradient -------------------------+-------------------------------------------------- Reporter: levill_r | Owner: Olena Team Type: enhancement | Status: new Priority: trivial | Milestone: Component: Milena | Version: 1.0 Keywords: | -------------------------+-------------------------------------------------- For the moment (rev. 1656), the Sobel gradient only works on 2-D images. We could generalize its definition to n-D (regular) images. For instance, a 3-D version is mentioned in http://www.aravind.ca/cs788h_Final_Project/gradient_estimators.htm. -- Ticket URL: <https://trac.lrde.org/olena/ticket/127> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image library.

[Olena] #123: Revamp general graph-based images (aka badly named « mesh images »)

by Olena

#123: Revamp general graph-based images (aka badly named « mesh images ») ----------------------+----------------------------------------------------- Reporter: levill_r | Owner: levill_r Type: task | Status: new Priority: major | Milestone: Olena 1.0ß Component: Milena | Version: 1.0 Keywords: | ----------------------+----------------------------------------------------- For starters, * Use `graph_based` prefix instead of `mesh`. * 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. * Rename « mesh elementary window » as « graph elementary neighborhood » (or adjacency? Check formal definitions to choose the right term.). * 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. -- Ticket URL: <https://trac.lrde.org/olena/ticket/123> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image library.
