2 Basic Concepts
Processes may have an arbitrary number of child processes. The resulting process
hierarchy defines the structure and flow control of the image analysis. Arranging
processes containing different types of algorithms allows the user to build a sequential
image analysis routine.

2.15.1 Algorithm
The algorithm defines the operation the process will perform. This can be generating
image objects, merging or splitting image objects, classifying objects, and so on. The
two main functions of algorithms are generating or modifying image objects and
classifying image objects. In addition to these, a set of other algorithms help to define all
necessary operations to set up an image analysis routine. The following functional
categories of algorithms exist:
• Process related operation
• Segmentation algorithms
• Basic Classification algorithms
• Advanced Classification algorithms
• Variables operation algorithms
• Reshaping algorithms
• Level operation algorithms
• Interactive operations algorithms
• Sample operation algorithms
• Image layer operation algorithms
• Thematic layer operation algorithms
• Export algorithms
• Workspace automation algorithms
