Step 2b of 7: From the Edge Intensities, find all Edges in the image:
Vertical (V) edge intensities:
Horizontal (H) edge intensities:
The Edges of the image:
Horizontal (H) edges are in Green,
Vertical (V) edges are in Red,
Blue means potentiall either H and/or V.
The reason that there are more edges on the right-hand
image than either of the left is because the edges in
the left-hand image are very, very light, so they don't
show up very well.
