\begin{itemize}
\item Facilitate access to OTB (QGIS widely use in the GIS community)
\item Avoid to duplicate efforts (use QGIS GUI, GIS features...)
\item Powerful features in QGIS processing (batch processing, Python scripting...)
\item Collaboration with the QGIS community is very positive
\item Support from QGIS developers
\item OSGeo \textit{power}
\item \href{https://www.youtube.com/watch?v=ufSQ2SgSIV4}{Demo}: \url{https://www.youtube.com/watch?v=ufSQ2SgSIV4}

\item ``Why I can't find the segmentation application in the QGIS processing panel?''
\item ``OTB applications seems to have slightly different names in QGIS?''
\item ``I give up OTB in QGIS...''
\item \alert{STOP!}
\item 2018: We need to improve the integration of OTB in QGIS
%\item Maintenance, Maintenance, Maintenance...
%\item Each version of otb needs to update list of descriptor files
%\item XML files which are hard to maintain.
%\item requires to update a blacklist and whitelist documents to list app that cannot be included and can be included
%\item needs manual update of these xml + followup on pull request
%\item works only with limited version of OTB (Not last release, mostly behind 3-4 releases)
%\item Nobody want to work on it from otb and qgis side. maintained by CS team
%\item Some applications were grouped, depending on their parameters : BinaryMorphologicalOperation (Closing, Dilate, Erode, Opening)
%\item Add new parameter in ParameterMultipleExternalInput processing, to use it in FusionOfClassifications
