IMAQ Skeleton VI

Owning Palette: MorphologyInstalled With: NI Vision Development Module

Starting from a binary image, calculates the skeletons of the particles within an image or the lines delineating the zones of influence of the objects (skeleton of an inverse image). The source image must have a border greater than or equal to 1.

Note This VI modifies the source image. If you need the original source image, create a copy of the image using the IMAQ Copy VI before using this VI.

IMAQ Skeleton

Mode specifies the type of skeleton to perform. The default is Skeleton L.

Skeleton L uses this type structuring element:

0	?	1
0	1	1
0	?	1

Skeleton M uses this type structuring element:

?	?	1
0	1	1
?	?	1

Skiz is an inverse skeleton (Skeleton L on an inverse image).

Image Src is a reference to the source image.

Image Dst is a reference to the destination image.

error in (no error) describes the error status before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.

	status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE.
	code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.
	source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.

Image Dst Out is a reference to the destination image. If Image Dst is connected, Image Dst Out is the same as Image Dst. Otherwise, Image Dst Out refers to the image referenced by Image Src.

error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.

	status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.
	code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.
	source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.
