3.4 Develop Rule Sets
The process of detecting objects in an image consists of a sequence of segmentation
and classification procedures. The sequence is defined in the rule set, which represents
the program code. It consists of a list of processes, which represent commands,
organized in a tree-like structure.
The typical workflow of the rule set development consists of three iterative activities:
• Use one the different ways of retrieving information about image objects.
• Edit one or more lines in the rule set.
• Run a branch of the rule set process tree for testing.
At the end you should have a rule set, that—when executed entirely on a image data—
detects the image objects of interest as defined by the image analysis task.
If you are already experienced in rule set development, you may continue with the
extended workflow of rule set development focusing the strategic approach.
