I would like to detect and isolate shapes, and for that would like to run a series of tests on a given x,y location to test for shape edge location/direction (to later follow it, even predict the direction (eventual line gaps, etc.)).
Does a cv2.kernel have to sweep the entire image, or is there some means of communicating with it with every pixel move? Is it possible to 'direct' a kernel (along a vector path, for example)?
