Extension Methods
  NameDescription
Public Extension MethodHasMethod
Checks whether an object implements a method with the given name.
(Defined by ExtensionMethods.)
Public Extension MethodIsEqual
Compares two objects for equality, performing an elementwise comparison if the elements are vectors or matrices.
(Defined by Matrix.)
Public Extension MethodToT

Remarks

Closing morphology operator equals to dilatation followed by erosion.

Applied to binary image, the filter may be used connect or fill objects. Since dilatation is used first, it may connect/fill object areas. Then erosion restores objects. But since dilatation may connect something before, erosion may not remove after that because of the formed connection.

See documentation to Erosion and Dilatation classes for more information and list of supported pixel formats.

Sample usage:

// create filter
Closing filter = new Closing( );
// apply the filter
filter.Apply( image );

Initial image:
