The Toolbox is composed by four groups of programs: tools, basic image operations and operators, first, second, and third level image operators.

### Basic Level

This groups holds the elementary operations and operators of Mathematical Morphology.### First Level

This group holds operators that uses only once each basic operator.### Second Level

This group holds operators that uses more than once each basic operator.### Third Level

This group holds operators that uses an a priori undefined number of basic operators.### Tools

This group holds some complementary functions.

For each program of the toolbox, there is an on line help associated, that gives the operator definition and a set of well known parameters to extract useful image information.
