-*** Quick introduction to OTB applications
-    - Orfeo ToolBox is a *library* offering remote sensing features
-    - Often several features of OTB must be combined within a processing chain
-    - Need for higher level interfaces (parameters, input and output data, logs ...)
-    - Each application corresponds to a high level function (segmentation, orthorectification, raster calculator ...)
-    - And corresponds to a C++ class (/otb::Application/) $\rightarrow$  library
-    - Plugin mechanism
-    - One can develop and distribute his/her own homemade applications
-
-*** OTB applications in Python
-    - Library called *otbApplication*
-    - 2 main classes can be manipulated:
-      - Registry: list available applications (or create some)
-      - Application: base class for all applications (interact with an
-        application
-    - Example:
-#+begin_src python
-import otbApplication 
-orth=otb.Registry.CreateApplication("OrthoRectification") 
-#+end_src
-
-*** Syntax 
-    - Getters
-#+begin_src python
-app.GetParametersKeys()
-#+end_src
-    - Setters
-#+begin_src python
-app.SetParameterString("in", argv[1])
-#+end_src
-    - How to launch an application
-      - Execute() -> wire the pipeline 
-      - ExecuteAndWriteOutput() -> wire the pipeline and write output
-
-*** Syntactic sugar
-    - Instead of:
-#+begin_src python
-ExtractROI.SetParameterInt('startx', 140)
-#+end_src
-
-    - Use: 
-#+begin_src python
-ExtractROI.STARTX=140
-#+end_src
-    - Upper case is mandatory for now
-
-*** In-memory connection
-    - Applications are often use as parts of larger workflow
-    - Heavy I/O operations generally in remote sensing image processing
-    - Connect output parameter from app1 to the input parameter of app2
-    - Available both in C++ API and Python
-    - Related to ITK/OTB streaming mechanisms
-
-*** NumPy bridge
-    - Plug OTB into any image processing chain in Python
-    - Use etImageFromNumpyArray() and SetImageFromNumpyArray() methods 
-

-
-*** Déroulement
-    Le TP consiste à mettre en place un script Python pour réaliser l'extraction
-    des surfaces en eaux dans une série d'images Sentinel-2 sur le zone de
-    /Laguna la nina/ au Pérou.
