Help with hough-lines please

[Jean-Pierre Coulon]

What is a binary edge image? Are tif or jpg images appropriate? is -stroke the tickness of the lines IM will search or that of the lines it will draw?

A good explanation of Hough lines is at http://www.imagemagick.org/discourse-se ... =4&t=25476

JPEG compression is lossy, which means it changes pixels. I suggest never using JPEG for any intermediate results.

Please, always provide your IM version and platform when asking questions, since syntax may differ. Also provide your exact command line and if possible your images.
