Real Images (bottle)

(1) No additional noise		(2) sigma=0,  epsilon=10%
(3) sigma=10, epsilon=0%	(4) sigma=10, epsilon=10%

Outputs of the New Operator on Bottle image

Corresponding new edge quality measure:
(1) 0.0639				(2) 0.0710
(3) 0.0700				(4) 0.0721

Comparision of Edge Maps

The new robust edge detector demonstates its ability in dealing with outliers and performs best when compared with the other operators. If only Gaussian noise is present, the tanh operator performs better.
