I have an image that has some distinct vertical lines in it.
Ive run a sobel gradient of the image (in the X direction only) and
I've gotten good responses to the lines. Unfortunately there is lot of
info in the image, so a lot of other things are detected. So I want to
extract the straight vertical lines that I have detected, from the
background stuff. Any ideas of how to do this without using the Hough
transform (as I need it to be as quick as possible)
I tried getting the orientation of each pixel , but as I am only doing
the gradient in the x direction, I only get two directions in
orientation; 0 and 90 so this is no use!
