 In order to perform classification, the user must train the algorithm by providing samples of every class. In this way, the classification algorithm creates a decision tree and applies it into the set of objects, classifying them. In order to perform classification, the user must train the algorithm by providing samples of every class.

-Firstly define your interest classes, and create nodes for them. All nodes must be in the same level, only one of them must have the //TerraAIDA_C45_Classifier// as Top Down Operator, and all the remaining nodes must have //No Operator//. Note: your classes of interest must be with the option **TopDown Multi-Class** selected.+Firstly define your interest classes, and create nodes for them.

-Select one operator to perform segmentation (//i.e. TerraAIDA_Baatz_Segmenter//), and press //Segment//. Afterwards, when the objects appear inside the image, select one interest class, and press //Collect Samples//. Then select all your samples to the interest class, and press //Collect Samples// again to stop the selection.
