To build a workspace to experiment with the Objects on Edges Off operator:
Select and Display the image $MMACH/viff/edgeoff.xv
using the operators User Defined and
Display Image. This image will be used as a base image to the opening
by reconstruction.
Select and Display the image $MMACH/viff/edges.xv
using the operators User Defined and
Display Image. This image will be used as a marker image to the opening
by reconstruction.
Generate a 3x3 Str.El. Flat Structuring Element like the following:
1 1 1
1 1 1 Structuring element used
1 1 1
Apply the Opening by Reconstr. operator using as first input edgeoff.xv, as second input edges.xv and as third input the structuring element.
Visualize the result.
Apply the Subtraction (mmach) operator to subtract the last result from the edgeoff.xv.
