Detailed Description

Morphological Structuring Elements.

In mathematical morphology, a structuring element is a shape, used to probe or interact with a given image, with the purpose of drawing conclusions on how this shape fits or misses the shapes in the image. It is typically used in morphological operations, such as dilation, erosion, opening, and closing, as well as the hit-or-miss transform.

Function Documentation

buildLineSE()

StrElt buildLineSE ( int  length, double  theta  )

inline

buildLineSE() - build a line structuring element with arbitrary length and angle.

The line is defined with the help of a Besenham algorithm

Parameters

[in]	length	: length of the structuring element
[in]	theta	: angle of the structuring element with the horizontal line

Returns

a line structuring element

merge()

StrElt merge ( StrElt  se1, StrElt  se2  )

inline

merge() - merge two Structuring Elements

Parameters

[in]	se1	: First structuring Element
[in]	se2	: Second structuring Element

Returns

a new structuring element with all points of se1 and se2
