I am working on a project where I need to implement road edge detection. This research paper suits my requirement in the best way, so I am studying it: http://imagine.enpc.fr/publications/papers/TIP10a.pdf
But I cannot understand the Gabor Filter equation they have used and also the set of parameter values they have used. Almost everywhere the Gabor Filter equation is different then theirs. If someone can explain, it would be great.
