Miscellaneous Operators

 

There are 3 operators in the Miscellaneous category:

{ } xxxxxxxx
Frame
For each plane in the 3D image volumes at the offset specified in the Src1 operand, the frame is filled with the constant specified by the Value operand. The vertical and horizontal borders of the frame are of thickness specified by the Width and Height operands, respectively.

Smooth
Performs a convolution with a ``flat'' rectangular structuring element of dimensions specified by the Width and Height operands. As the structuring element is only 2D, it can be applied on any orthogonal plane as specified by the Axis operand.

Cluster
Performs a planar connected components analysis such that each pixel in the result image has a value equal to the number of pixels in the cluster to which it belongs. Only those pixels whose value lies within the inclusive range, specified by the Ceiling and Floor, are candidates for membership in a cluster. A pixel is deemed to be a member of a cluster based on 8-neighbor planar connectivity.
