IMAQ Separation VI
Owning Palette: MorphologyInstalled With: NI Vision Development ModuleSeparates touching particles, particularly small isthmuses found between particles. This VI performs n erosions where n equals Nb of Erosion and then reconstructs the final image based on the results of the erosion. If an existing isthmus is broken or removed during the erosion process, the particles are reconstructed without the isthmus. The reconstructed particles, however, have the same size as the initial particles except that they are separated. If no isthmus is broken during the erosion process, the particles are reconstructed as they were initially found. No change is made. The source image must be an 8-bit binary image and have a border greater than or equal to 1pixel.

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. |
 |
Square/Hexa (Square) specifies whether to treat the pixel frame as square or hexagonal during the transformation. The default is square. |

 |
Image Src is a reference to the source image. |
||||||
|
Image Dst is a reference to the destination image. |
||||||
 |
Nb of Erosion specifies the number of erosions that are used to separate the particles. The default is 1. |

 |
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.

Structuring Element is a 2D array that contains the structuring element to apply to the image. The size of the structuring element (the size of this array) determines the processing size. A structuring element of 3 × 3 is used if this input is not connected. |
||||||
 |
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.
