======= TerraAIDA Operator Development =======

This is an auxiliary document to help developers to be able to build their own InterIMAGE operators by reusing the base of functions/classes built by the TerraAIDA developers team.

==== InterIMAGE interaction ====

This topic describes the interaction mechanism between the InterIMAGE engine core and an operator. It provides only the minimum set of details required by a TerraAIDA operator. More detailed information can be found at the [[http://www.lvc.ele.puc-rio.br/projects/interimage/|InterIMAGE main site]].

== InterIMAGE analysis scheme ==

  *The semantic network
  *The top-down analysis step
  *The bottom-up analysis step

== Operator interface ==

  *Operator execution environment
  *Operator description file (.OP)
  -Operator action region bounding box
  -Action region mask file (optional)
  -Output result label image
  -Output result hypothesis description XML file
  -Other auxiliary parameters

==== TerraAIDA aperators auxiliary classes and functions ====

This topic describes the base of functions/classes built by the TerraAIDA developers team to allow the proper interpretation of the parameters received from the InterIMAGE engine core to a TerraLib programming environment. Only a few set of TerraLib features will be described. For more information please consult the [[http://www.terralib.org|TerraLib site]].

== TerraLib interaction ==

  *TerraLib matricial support
  *TerraLib vectorial support

== Project structure ==

  *Directory disposition
  *Platform compilation issues
  *Testing support (experimental)

== Operators base library ==

  *Classes and hypothesis support data structures
  *Support functions

==== A simple operator building example ====

This topic describes a simple operator build example using the TerraAIDA support.

Just like in [[creating_operators]] but much more simple. Maybe we could build a simpler operator an keep it inside the CVS repository too.
