edgedetect: remove unused and useless functions.

Browse source 
The cvSmooth cvNot functions and do not have the correct input parameters.
Furthermore, cvSmooth function is not necessary for edge detection,
because the Canny function makes the step of smoothing the image.
And cvNot function is useless because there aren't changes if this
function is eliminated.
