Input parameters

Documentation illustration (illustration unavailable in the archive). Image Src : class, type accepted U8.
Documentation illustration (illustration unavailable in the archive). Structuring Data : array, 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.

Documentation illustration (illustration unavailable in the archive). Morphology Parameters : cluster,

Documentation illustration (illustration unavailable in the archive). Operation : enum, specifies the type of morphological transformation procedure to use.

- - AutoM : auto median
  - Close : dilation followed by an erosion
  - Dilate : dilation (the opposite of an erosion)
  - Erode : erosion that eliminates isolated background pixels
  - Gradient : extraction of internal and external contours of a particle
  - Gradient out : extraction of exterior contours of a particle
  - Gradient in : extraction of interior contours of a particle
  - Hit miss : elimination of all pixels that do not have the same pattern as found in the structuring element
  - Open : erosion followed by a dilation
  - PClose : a succession of seven closings and openings
  - POpen : a succession of seven openings and closings
  - Thick : activation of all pixels matching the pattern in the structuring element
  - Thin : activation of all pixels matching the pattern in the structuring element

Documentation illustration (illustration unavailable in the archive). Square/Hexa (Square) : boolean, specifies whether to treat the pixel frame as square or hexagonal during the transformation.
Documentation illustration (illustration unavailable in the archive). Iteration : integer, is the number of times the VI performs a dilate or erode operation.
