Edge Direction Preserving Smoothing
-
Simple smoothing destroys the local contrast along edges
-
One of the reasons is that the filters ignore the local orientation
of edges
-
HALCON 7.1 offers two new filters that apply the
smoothing only in the direction of the edge
- Therefore, the
edges are being preserved while noise is being removed
