External Tool Edge Enhancement

Performs an edge enhancement operation based on different Methods: Inner gradient, Outer gradient, Gradient (Morphological) and Top hat. Structuring Elements of 2D SQUARE, 3D CUBE and 3D CROSS are available at the sizes of 3, 5, 7, and 9 pixels.

It is a morphological contouring tool and the processing is based on voxel wise morphological operations: erosion and dilation and image subtraction. The Methods are summarized in the table below:

Inner gradient

the difference between the input image and its erosion using the specified structuring element

Outer gradient

the difference between the dilation and the input image using the specified structuring element

Gradient (morphological)

the difference between the dilation and the erosion using the specified structuring element

White Top hat

the difference between the input image and its opening using the specified structuring element

Black Top hat

the difference between the closing and the input image using the specified structuring element
