DGtal dev meeting (June 25th, 2014)

Package review

General remarks

• namespace policy
  • create functors::, gathers all functors/functions into this namespace
  • remove detail::, keep details::
  • put all standalone functions into functors:: or details::
  • question: namespace concepts:: ?

Base package

• Iterators

  • some iterators are well standardized (STL/boost + DGtal): GridCurve, DSL, perhaps some image containers)
  • but most DGtal iterators are not standardized
  • Action (M1): standardize Image, Domain, DigitalSurface

• "smart" pointers and parameter passing

  • use ConstAlias, Alias, Clone at most
  • Action (S2): unify some smart pointers
  • Action (M1): check other packages (DigitalSurface, etc)

• Functors:

  • Action (S1) doc on basic functors and functors of other packages.

• Exceptions ?

  • Action (M2) check some assertions and replace them by exception

Kernel package

Graph package

Mathematical package

Image package

IO package

Former feature requests

• Linear algebra (nD) => Matrix, Vector, EigenDecomposition + package dec (linalg)
  • doc missing
• polytopes (Rn, Qn) => few things, LatticePolytope2D
• affine transformations => only matrices
• bindings with morpho math packages => ?
• image processing packages => binding ITK, DICOM reader, ImageMagick reader/writer
• geometric primitives (fuzzy, higher degree) => Plane recognition (fuzzy in the Hausdorff sense)
• graph algorithms => visitors (depth-first, breadth-first, euclidean distance first), watershed, binding boost::graph (DGtal graphs can be wrapped as boost graphs)
• chamfer or graph-based distances => LUT morpho math tool (not in library)
• medial axis => DT, Voronoi by separable algos + ?
• partition models => LabelledMap (K different characteristic functions stored compactly),
• video => nothing
