 ====== TerraAIDA Operators Documentation ======
 Operators reference version: 1.0.5
+InterIMAGE is a multi-platform framework, written in C++, currently with implementations for LINUX and Windows operational systems. Moreover, InterIMAGE provides support for the integration of image processing operators in the interpretation process and, as such operators are treated as external programs by its control mechanism, they can be coded in any computer language, and even in proprietary programs. The InterIMAGE framework offers, nonetheless, a repository of operators, called TerraAIDA ([[http://www.dpi.inpe.br/terraaida]]), assembled with software classes and functions supplied by the [[http://www.terralib.org/|TerraLib]] library.

 **Multi-Class support**
-Yes. If you select //true// in the "Top Down Multi-Class" option, you must create another node in the same level with a corresponding opposite name, with prefix "n-". For example, if this class name is "MyClass" the opposite class name will be "n-MyClass". Hypothesis discarded by this operator will be classified as "n-MyClass".
