Settings

The GrayMorph Filter properties page, in default setting, allows the modification of all properties:

• Iterations - The number of times the morphological operator is performed on the input image. If you enter a value less than one, one iteration is performed.

Default: 1

• MorphOpCode - The morphological operator (function) that this step performs when run:

• ERODE (Default) - Grayscale minimum function. The output pixel is set to the value of the minimum pixel in the neighborhood.

• DILATE - Grayscale maximum function. The output pixel is set to the value of the maximum pixel in the neighborhood.

• OPEN - Erosion followed by dilation.

• CLOSE - Dilation followed by erosion.

• GRADIENT - The output pixel is set to the difference between the maximum and the minimum pixels in the neighborhood. (MAX-MIN).

• TOPHAT - The difference between the original image and the image after it has been OPENed (original minus OPENed).

• WELL - The difference between the image after it has been CLOSEd and the original image. (CLOSEd minus original)

• Polarity - The polarity of the pixels to be processed. For example, when Polarity is set to Light, dilations will dilate light colored pixels:

• Light - Pixels of interest are light colored.

• Dark - Pixels of interest are dark colored.

• Show Output Pixels - Flag indicating that the results of the GrayMorph step will be displayed graphically on the output target monitor.

• Custom Structuring Elem - Allows you to specify a custom Morphology kernel that is different from the default 3x3 kernel.
