iterations is limited to 35 along the x and y axes so that the square shape’s corners fit inside the circle.
Defects at the top, bottom, left, and right may not be found.
Using a circle shape would solve this problem, but a perfect circle is slow to process, so an octagonal shape
is used. (The figure on the right.) The execution time is only 40% greater to accomplish the required 43 iter-
ations within the octagon than within a square.
Morphology Dilate
In the Image Filtering Drawer
The Morphology Dilate tool performs a standard dilation operation on the white parts of the image. (See
“Morphology” on page 3-52 for more details.)

Input Name What it is
Input Image Linked Image
Tool Origin The tool’s origin relative to the entire image space
Shape List The desired region of the image to search. If no shape is defined, the
entire image is processed.
Number of Itera-
tions
The number of times to perform the operation. If zero is entered, the tool
just copies the input image to the output.
Morphology Shape Defines the shape of the neighborhood around each pixel that is
searched to find the output pixel value. See “Morphology Shape” on
page 3-53.
