This example is optimised for straight lines. For a generalised transform, one would probably have to do a search through the full parameter space. Then the 'for'-loops might kill performance. I guess the best would be to try and find an article that has an algorithm for the specific case you are interested in.

I've been giving this some thought and reading more about the hough transform. I'm new to image processing but I think I'm getting a better understanding of how it works. How about including a hough transform function in scipy? It seems like a useful function to have in the image processing toolbox, and the line detection seems fairly straightforward. Stefan's implementation already looks like a great start. Is this something that would be useful for others? (Stefan - sorry for the double mail) Stephen
