So we fill img with the value 'a': +\begin{lstlisting}[frame=single] + level::fill(inplace(imga), 'a'); +\end{lstlisting} + +The "fill" algorithm is located in the sub-namespace "level" since this +algorithm deals with the "level" of site values. + +Note that the term "level" refers to the fact that an image can be considered as +a landscape where the elevation at a particular location/site is given by +the corresponding site value. + +The full name of this routine is "oln::level::fill". To access to a particular +algorithm, the proper file shall be included. The file names of algorithms +strictly map their C++ name; so oln::level::fill is defined in the file +"oln/level/fill.hh". + +Most algorithms in Olena are constructed following the classical scheme: "output +algo(input)", where the input image is only read. However some few algorithms +take an input image in order to modify it. To enforce this particular feature, +the user shall explicitly state that the image is provided so that its data is +modified "inplace". The algorithm call shall be "level::fill(inplace(ima), +val)". When forgetting the "inplace(..)" statement it does not compile. + +We then define below a second image to play with. As you can see this image has +data for the sites (5, 5) to (14, 14) (so it has 100 sites). The definition +domain of a 2D image can start from any sites, even a negative one. + +\begin{lstlisting}[frame=single] + image1d<char> imgb(5, 5, 14, 14); + + // We initialize the image values. + level::fill(inplace(imgb), 'b'); + + // Last we now paste the contents of img3b in img3a... + level::paste(imgb, inplace(imga)); + + // ...and print the result. + debug::println(imga); +\end{lstlisting} + +Before pasting, the couple of images looked like: + +//FIXME : ajouter des zolies zimages. + +so after pasting we get: + +//FIXME : ajouter des zolies zimages again. + +With this simple example we can see that images defined on different domains (or +set of sites) can interoperate. The set of sites of an image is defined and +can be accessed and printed. The following code: + +\begin{lstlisting}[frame=single] + std::cout << "imga.domain() = " << imga.domain() + << std::endl; + std::cout << "imgb.domain() = " << imgb.domain() + << std::endl; +\end{lstlisting} + +Gives: +\begin{lstlisting}[frame=single] + imga.domain() = { (0,0) .. (19,19) } + imgb.domain() = { (5,5) .. (14,14) } +\end{lstlisting} + +The notion of site sets plays an important role in Olena. Many tests are +performed at run-time to ensure that the program is correct. + +For instance, the algorithm level::paste tests that the set of sites of imgb +(whose values are to be pasted) is a subset of the destination image. + + +\begin{figure}[ht!] + \begin{lstlisting}[frame=single] +template <typename I> +void fill(I& ima, mln_value(I) v) +{ + mln_piter(I) p(ima.domain()); + for_all(p) + ima(p) = v; +} + \end{lstlisting} + \caption{Implementation of the fill routine.\label{fig:fill_impl}} +\end{figure} + + +\begin{figure}[ht!] + \begin{lstlisting}[frame=single] +template <typename I, typename J> +void paste(const I& data, J& dest) +{ + mln_piter(I) p(data.domain()); + for_all(p) + dest(p) = data(p); +} + \end{lstlisting} + \caption{Implementation of the paste routine.\label{fig:paste_impl}} +\end{figure} + + +\section{Working with parts of an image} + +Sometime it may be interesting to work only on some part of the image or to +extract only a sub set of that image. Olena enables that thoughout out the +operator '$|$'. + +Three kinds of that operator exist:\\ + +\begin{tabular}{|l|l|l|l|p{4cm}|} +\hline +Prototype & Comments \\ \hline + +Image $|$ Sub Domain & Create a new image.\\ \hline +Image $|$ Function\_p2b & Do not create a new image but create a morpher.\\ +\hline +Function\_p2v $|$ Sub Domain & Do not create a new image but create a morpher.\\ +\hline +\end{tabular} \\ + +A Sub Domain can be a site set, an image or any value returned by this +operator. +For a given site, Function\_p2v returns a Value and Function\_p2b returns a +boolean. These functions. are actually a sort of predicate. You can easily get +of function of function\_p2v kind thanks to pw::value(Image). It returns the +point to value function used in the given image. C functions can also be used as +predicate by passing the function pointer. + +You can easily get a function\_p2b by comparing the value returned +by a function\_p2v to another Value. +The following sample code illustrates this feature. + +In this section, all along the examples, the image "ima" will refer to the +following declaration: +\begin{lstlisting}[frame=single] + bool vals[6][5] = { + {0, 1, 1, 0, 0}, + {0, 1, 1, 0, 0}, + {0, 0, 0, 0, 0}, + {1, 1, 0, 1, 0}, + {1, 0, 1, 1, 1}, + {1, 0, 0, 0, 0} + }; + image2d<bool> ima = make::image2d(vals); +\end{lstlisting} + +A simple example is to fill only a part of an image with a specific value: +\begin{lstlisting}[frame=single] +p_array2d<bool> arr; + +// We add two points in the array. +arr.append(point2d(0, 1)); +arr.append(point2d(4, 0)); + +// We restrict the image to the sites +// contained in arr and fill these ones +// with 0. +// We must call "inplace" here. +fill(inplace(ima | arr), 0); + + +mln_VAR(ima2, ima | arr); +// We do not need to call "inplace" here. +fill(ima2, 0); +\end{lstlisting} + +The two next examples extract a specific component from an image and fill a new +image with red only in the extracted component's domain. +\begin{lstlisting}[frame=single] + using namespace mln; + using value::int_u8; + using value::rgb8; + + // Find and label the different components. + int_u8 nlabels; + image2d<int_u8> lab = labeling::blobs(ima, c4(), nlabels); + + // Store a boolean image.

Here is a (non comprehensive) list of things to fix: * In source:trunk/mln/core/ `mln::window` vs `mln::neighb_` (full name vs short name + no trailing underscore vs trailing underscore) * Likewise, we have `mln::window` (without « `_` ») but `mln::point_`, etc. * In source:/trunk/milena/mln/accu/median.hh the class does not have any trailing underscore, whereas other accumulators from source:/trunk/milena/mln/accu/ have one. * graph- and complex-related domain-iterators have trailing underscores, whereas their vicinity counterparts does not. = Traits macros = * Should we use `mln_sum(V)` or `mln_trait_value_sum(V)` in the library code? I (Roland) think so. = Neighborhoods = * The terms/prefixes `nbh`, `neighb` and `neighborhood` are used inconsistently throughout the project. Here are the files that should be checked (and possibly renamed), as of revision r1859: * source:trunk/milena/mln/core/clock_neighb.hh * source:trunk/milena/mln/core/clock_neighb2d.hh * source:trunk/milena/mln/core/concept/doc/neighborhood.hh * source:trunk/milena/mln/core/concept/neighborhood.hh * source:trunk/milena/mln/core/graph_elt_neighborhood.hh * source:trunk/milena/mln/core/graph_neighborhood_piter.hh * source:trunk/milena/mln/core/line_graph_elt_neighborhood.hh * source:trunk/milena/mln/core/line_graph_neighborhood_piter.hh * source:trunk/milena/mln/core/neighb.hh * source:trunk/milena/mln/core/neighb1d.hh * source:trunk/milena/mln/core/neighb2d.hh * source:trunk/milena/mln/core/neighb3d.hh * source:trunk/milena/mln/metal/has_neighborhood.hh * source:trunk/milena/mln/neighb/ * source:trunk/milena/mln/trait/neighborhood.hh Comment: Generalize this ticket. -- Ticket URL: <https://trac.lrde.org/olena/ticket/133#comment:1> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image processing library.

2201: Update README.branches.

by Roland Levillain

Un dessin vaut mieux que mille mots. :-) Tant qu'on dépend de Subversion, il faut qu'on essaie de maintenir ce fichier. Il aurait été encore mieux d'aller renseigner les méta- données SVN des différentes révisions (peut-être n'est-il d'ailleurs pas trop tard, mais je n'en sais rien) pour en déduire ce schéma, mais bon, le mieux est l'ennemi du bien. Dans tous les cas, je pense qu'il faut qu'on se parle avant de décidé d'un merge (dans un sens ou dans l'autre). Et une fois que branche cleanup-2008 aura été complètement réintégrée dans trunk, je pense qu'il faudra la détruire, puis utiliser des branches Git dans les dépôt perso, qui offrent moins de risques.
