"image" variable in processImage

[LovroG05]

Where does the image variable that you return from processImage come from?
i do not see it defined anywhere, but it is used down the line.

thanks

The image that processImage() returns is for debug purposes. I used them to see the resulting image for each process that it had gone through. To detect lane lines, the canny image is used, but before we get to that, the image has to go through some other processing i.e. blur and so on.
