image is basically a grayscale in the color so you could predict the color from the grayscale or you have you have the depth image then you have the color image and you could try to predict the depth image from the color image where let's say you're recording everything from your Kinect so it could be source separation and then you try to predict the separate equation so that is the first principle the second principle is we're going to do something like visual common sense to us where it's more ad hoc and you just trying to create tasks
