| - | 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. | + | Afterwards create a structure to perform segmentation.
