//! This class is intended to calculate shape free bounds
|

//! properties.
|
|
//! This class provides the following functionalities:
|
|
//! - calculates area of the contour,
|
|
//! - calculates perimeter of the contour,
|
|
//! - calculates ratio of average length to average width of the
|
|
//! contour,
|
|
//! - estimates average width of contour,
|
|
//! - finds the notches (narrow 'V'-like sub-contour) on the
|
|
//! contour.
|
|
//!
|
|
//! For getting free bounds this class uses
|
|
//! ShapeAnalysis_FreeBounds class.
|
|
//!
|
|
//! For description of parameters used for initializing this
|
|
//! class refer to CDL of ShapeAnalysis_FreeBounds.
|
|
//!
|
|
//! Properties of each contour are stored in the data structure
|
|
//! ShapeAnalysis_FreeBoundData.
