11.23. ITK Dilate Object Morphology Image Filter
Grows (dilates) a single labeled object in a mask image — a fast single-object variant of binary dilation.
Group (Subgroup)
ITKBinaryMathematicalMorphology (BinaryMathematicalMorphology)
Description
This filter dilates one object in a mask image. Pixels whose value equals the Object Value are treated as the object (foreground); all other pixels are background. Wherever an object pixel is adjacent to a background pixel, the structuring element (the probe shape swept over the image) is centered on the object pixel and the background pixels it covers are set to the object value, growing the object outward. It is intended for masks that contain a single object; to dilate any of several segment values in a general segmented image, use ITK Binary Dilate Image Filter.
Parameter Guidance
Object Value — the pixel value of the object to dilate. Default 1.
Kernel Radius — the radius of the structuring element, in pixels (one value per axis). The object grows by this amount.
Kernel Type
The Kernel Type parameter selects the structuring element shape:
Annulus [0]: A ring-shaped structuring element.
Ball [1]: A spherical structuring element (default). Most commonly used for general morphological operations.
Box [2]: A rectangular/cuboid structuring element.
Cross [3]: A cross-shaped structuring element.
Required Input Sources
Operates on a binary/single-object mask image — typically the output of a thresholding filter such as ITK Binary Threshold Image Filter or Multi-Threshold Objects.
