This is an attempt at using opencv distanceTransform to try to turn an image sort of inside out. This example runs nowhere near real time because the distance transform mask is moving and forces recomputation on every step, a cv::remap version would do much better but not be as interesting. I think I should try to look into ways of cheaply modifying remap maps.
