I remember seeing this/such papers elsewhere. They have appeared in conference/papers for the last few years too. Here I'm suggesting untrained coloring of 'new' images from existing though, so maybe what I'm asking is a simpler problem? "Transferring colors from base (new) image to target (old) image using such and such sampling" would be how I would put my problem. The paper you link to would be more "learning to transfer colors by looking at how grayscale images transfer to color", right? Am I missing something?
