[mmserot] [Up] [mmsesum] Structuring Elements

mmseshow
Display a structuring element as an image.

Synopsis

function y = mmseshow ( B , option )

Input

B Structuring Element
option String

Default: 'NORMAL'

'NORMAL', ' EXPAND' or ' NON-FLAT'

Output

y Image Gray-scale (uint8 or uint16) or binary image

Description

mmseshow used with the option EXPAND generates an image y that is a suitable graphical representation of the structuring element B. This function is useful to convert a structuring element to an image. The origin of the structuring element is at the center of the image. If B is flat, y is binary, otherwise, y is signed int32 image. When using the option NON-FLAT, the output y is always a signed int32 image.

Examples

Flat structuring element
b=mmsecross(3);

mmseshow(b)
