that's what 3 researchers at the max planck institute for intelligent systems into began germany want to determine. this system represents the movement of an object in different colors and different degrees of brightness depending on the perceived direction and the speed it's going in. your car is moving to the right then and then your optical is going look like yellow in the color map and the fosters move the brighter the colors so if it's moving right at a really high speed then you see it like a bright yellow thing and then if it's moving slowly then it's more towards the right to me how like a color wheel representation which sort of like shows the corresponding civil lawsuit is but stuff like happened in the video and objects move. on a rock run john that's one way the optical fly are it represents that in yellow. if you go the other way it turns purple. the computer vision system also predicts the 5 in me front of all jets it's identified as the color of the head still moving forward or is it slowing to a stop that's key to preventing collisions for example. and it has to do all
