1.3 Segmentation and classification
The first step of an eCognition image analysis is to cut the image into pieces, which serve as building
blocks for further analysis – this step is called segmentation and there is a choice of several
algorithms to do this.
The next step is to label these objects according to their attributes, such as shape, color and relative
position to other objects. This is typically followed by another segmentation step to yield more
functional objects. This cycle is repeated as often as necessary and the hierarchies created by these
steps are described in the next section.
