#160: Revamp complexes ----------------------------+----------------------------------------------- Reporter: levill_r | Owner: Olena Team Type: enhancement | Status: new Priority: minor | Milestone: Olena 1.0 Component: Milena | Version: 1.0 Keywords: cleanup rename | ----------------------------+----------------------------------------------- * Move complexes from `mln/core/` to `mln/topo/`. * The '''dynamic''' access(es) to the set of ''n''-faces of a complex (e.g., `mln::complex::nfaces(unsigned)`) has (have) a linear complexity! We should get rid of that. We could create an index at the creation of the complex, mapping dynamic dimension numbers to the corresponding (static) mixin/data. Ask Roland for details. -- Ticket URL: <https://trac.lrde.org/olena/ticket/160> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image processing library.

[Olena] #188: Implement more windows, neighborhoods, and corresponding iterators for complex-based images

#188: Implement more windows, neighborhoods, and corresponding iterators for complex-based images ----------------------+----------------------------------------------------- Reporter: levill_r | Owner: levill_r Type: task | Status: new Priority: minor | Milestone: Olena 1.1 Component: Milena | Version: 1.0 Keywords: | ----------------------+----------------------------------------------------- This ticket is a sequel to #162. In addition to the neighborhoods, windows, and iterators for complex-based images from #162, implement windows/neighborhoods (and corresponding iterators) returning the following elements (where ''n'' is a (fixed) dimension and ''p'' a psite on an ''n''-face). `complex_cell_window`:: the set of the faces in the « cell » including ''p'' (named « ''p''-hat » in couprie.08.pami), i.e. the set of all ''m''-faces transitively adjacent to ''p'', where ''m'' is in [0, ''n''-1].[[BR]] In that definition, ''p'' is said adjacent to an ''m''-face ''q'' if there is a sequence (''m,,1,,'', ''m,,2,,'', ..., ''m,,k,,'') of faces so that * ''m,,1,,'' is an (''n''-1)-face adjacent to ''p'' ; * ''m,,2,,'' is an (''n''-2)-face adjacent to ''m,,1,,'' ; * ... (and so on) * ''m,,k,,'' is an (''m''+1)-face adjacent to ''q''. `complex_boundary_cell_window`:: Likewise, but excluding ''p'' (named « ''p''-hat* » in couprie.08.pami). And maybe: `complex_lower_dims_connected_window`:: the set of ''n''-faces sharing a (''n''-1)-face or (''n''-2)-face etc. (by transitivity) with ''p'' (is it useful?); `complex_higher_dims_connected_window`:: the set of ''n''-faces sharing a (''n''+1)-face or (''n''+2)-face etc. (by transitivity) with ''p'' (is it useful?); * what else? As in #139, * we might want to factor things using implementation classes: * ``mln::internal::complex_vicinity`` * ``mln::internal::complex_vicinity_piter`` (we might even be able to factor them with graph-based ones); * we could have one or several generic classes, using static or dynamic predicates, to implement those windows and neighborhoods. Note that some of these iterators might implement operators on complexes, see http://en.wikipedia.org/wiki/Simplicial_complex#Closure.2C_star.2C_and_link.

#185: Unify algorithms morpho::skeleton_constrained and topo::breadth_first_thinning -------------------------+-------------------------------------------------- Reporter: levill_r | Owner: levill_r Type: enhancement | Status: new Priority: major | Milestone: Olena 1.0 Component: Milena | Version: 1.0 Keywords: | -------------------------+-------------------------------------------------- Two (very similar) skeletonization algorithms have been developed: 1. source:trunk/milena/mln/morpho/skeleton_constrained.hh 2. source:trunk/milena/mln/topo/skeleton/breadth_first_thinning.hh The first algorithm is probably a bit more generic, as it takes a priority function as input. It has not been tested on complex-based images (known to be supported by the second algorithm). Unify both algorithm (within `topo/skeleton/`), probably using a canvas. Some elements like the constraint or the priority function should provide default values; the only mandatory arguments should be the input image, the neighborhood and the simplicity function. Do not forget to move/adjust corresponding tests/programs accordingly. -- Ticket URL: <https://trac.lrde.org/olena/ticket/185> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image processing library.
