Problematic edge detection

Hi Steven,

I notice when i use the sobel edge detection on an image of any object for example a rectangular piece of wood where the top half of the wood is above the horizon and the bottom half below, instead of getting two vertical edges ie. the left and right edge i get four edges. The left and right edges are split into two by the horizon so i get two edges instead of one for the left side of the wood and the same goes for the right edge. Is there any way to overcome this problem?

Can you post the original image where you see this issue?

Its hard to tell what's really happening without an example.
