how to define a new kernel function? how to find an optimal threshold? how to classify the road from background? Basically?

The answers to those questions can be found in the papers and algorithms listed here: VisionBib. But it all depends on what your images look like, and what you want to do. There is no one single "optimal threshold" selection algorithm or kernel that works with all images in the world all of the time. And saying "I want to find roads" doesn't really narrow it down too much, at least not enough for us to answer you. I'm sure you've heard in the news about "self-driving cars" - well, I'm sure that's tens of thousands of lines of code that many, many teams of brilliant people have been working on for two decades. It's not going to be some hundred line chunk of code that we can give you here. Good luck though.
