 ====== Multiresolution Segmentation ======
-This example shows how to perform multiple segmentation in the image, using coarse and fine resolutions. We use the three methods for segmentation currently available in InterIMAGE, namely //Region Growing//, //Baatz// and //Checkerboard//.

 Create a new project called "multiresolution_segmentation".
-After that create a structure to perform segmentation. We firstly created a node called "coarse_segmentation" which applies the //TerraAIDA_Region_Growing_Segmentation// operator. We also created three child nodes, called "fine_segmentation", "fine_checkerboard", and "background" with //TerraAIDA_Baatz_Segmentation//, //TerraAIDA_Checkerboard_segmentation// and "Dummy Top Down" operators respectively. The node "background" will be associated to the remaining elements.
