 ====== TerraAIDA Operators Documentation ======
-Operators reference version: 1.0.5
+Operators reference version: 1.0.6
 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.

 | Polygons Min Area     | Integer | Generated polygons minimum allowed area (pixels).  |  | Only polygons with area greater than the supplied values will generate hypothesis. |
 | Dummy Value (no data)     | Floating point | The dummy value from input images. |  | If not present, all image data will be processed. |
-| Arithmetic Expression     | String | One valid arithmetic expression, formed by a combination of the following elements, separated by spaces. | Operators: +, -, *, /, Real Numbers, Raster indexes and bands R0:1, R1:2 | Example: Quickbird-2 image with bands (0=B,1=G,2=R,3=NIR), the NDVI is calculated by ( R0:3 - R0:2 ) / ( R0:3 + R0:2 ). |

 | Morphological Filter Iterations | Integer | Number of morphological (mode) iterations applied to the result. | Greater or equal to 0. | The use of a value greater than or equal to 1 is advised to avoid the creation of to small hypothesis |
 | Training Set File | *.shp | A file with training samples for supervised classification. | The file must be in the InterIMAGE region format. | |
