#146: Ensure the output value type is large enough in labeling algorithms -----------------------+------------------------------- Reporter: levill_r | Owner: levill_r Type: defect | Status: new Priority: major | Milestone: Olena 2.2 Component: Milena | Version: 1.0 Resolution: | Keywords: overflow labeling -----------------------+------------------------------- Changes (by levill_r): * milestone: Olena 2.1 => Olena 2.2 Old description:

Most labeling algorithm do not check that the output value is large enough to hold the whole set of labels. This is at least the case in

* source:trunk/milena/mln/labeling/regional_minima.hh * source:trunk/milena/mln/labeling/regional_maxima.hh * source:trunk/milena/mln/morpho/watershed/flooding.hh (and its ancestor source:trunk/milena/mln/morpho/meyer_wst.hh)

These algorithms should trigger an error if this happens, even if the output value type is not equipped to detect overflows.

To do:

1. Write (small) test cases for each algorithm. 1. Choose a sound behavior (exceptions?). 1. Apply the required modifications.
