Thickening Operator
Building the Cantata Workspace
To build a workspace to experiment with the thickening operator:
- Select and Display the image $MMACH/viff/thinthick.xv
using the operators User Defined, Expand and
Display Image. Expand is used to make the pixels
look larger as the original image is very small.
- Build the two Structuring Elements A and B using two
3x3 Str.El.
operators.
- Use operators
Sup-Gen.
and
Union
Exercises
- Repeat the same experiment but thickening pixels in places where
exists a top and bottom pixel equal to one.
- Repeat the same experiment by thickening pixels in places where
exists a pixel at its right side.
- Are the thickening operators used in this experiment and in the above
exercices homotopic?
- Repeat the same experiment to thick pixels in places where exits
at least one 4-connected neighbor pixel equal to one.
(Hint: use the operator
Rotate Str. El.)
