class StructuringElement

Class for structuring elements This class is used either for mathematical morphology procedures or for median filtering

Inheritance:

Public

	Public methods int getConnectivity ( void ) get the connectivity of the structuring element void setArrayOfPoints ( typeStructuringElementPoint *l ) set a pointer to the list of neighbors typeStructuringElementPoint* getArrayOfPoints ( void ) get the pointer to the list of neighbors void setNumberOfPoints ( const int n ) set the number of neighbors int getNumberOfPoints ( void ) get the number of neighbors StructuringElement& operator= (const StructuringElement& s) replicates the structuring element void convertToList ( void ) Transform any structuring element into a list of neighbors void inverse ( void ) Invert the structuring element, ie compute the symetric
	Constructors StructuringElement ( const CONNECTIVITY_TYPE C=TWENTY_SIX_CONNECTIVITY ) throw( InvalidElement ) Create structuring element from connectivity StructuringElement ( const int x, const int y, const int z = 1 ) throw( InvalidElement ) Create structuring element from a rectangular neighborhood The center is supposed to be x/2 y/2 z/2 StructuringElement ( const char *name ) Create structuring element from an image whose path is given as argument StructuringElement ( const Inrimage *image ) throw( InvalidElement ) Create structuring element from an image StructuringElement ( const StructuringElement &elem ) Create an replica of elem
	Destructor virtual ~StructuringElement () deallocates image buffer
