IMAQ RemoveParticle VI
Owning Palette: MorphologyInstalled With: NI Vision Development ModuleEliminates or keeps particles resistant to a specified number of 3 x 3 erosions. The particles that are kept are exactly the same shape as those found in the original source image. The source image must be an 8-bit binary image.
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. |
Connectivity 4/8 (8) specifies the type of connectivity used by the algorithm for particle detection. The connectivity mode directly determines whether an adjacent pixel belongs to the same particle or a different particle. The default is 8. The following values are possible:
|
|||||||
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. |
|||||||
Number of Erosion specifies the number of 3 x 3 erosions to apply to the image. The default is 2. |
|||||||
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.
|
|||||||
Low Pass/High Pass (Low) specifies whether the objects resistant to n erosions are discarded or kept (default). |
|||||||
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.
