Hey everyone, I've been trying to find out how to get this effect:

http://www.cs.utah.edu/~vpegorar/cou...arch_hough.png

and I found a "guide" on how to do it http://www.cs.utah.edu/~vpegorar/cou...6/Assignment4/ (bottom of the page)

I can get the line defined image fine, but I have no idea what effect/filters to use, tried finding a plugin or even a program solely for doing the hough transform but I couldn't find anything.

So any help would be awesome thanks
