It is not the same thing but kind of reminds of my naive and obvious(meaning something that came up when drinking beer) idea of generating bunch of variations of your labeled data in cases when you do not have enough. Let's say you only have one image of dog, you generate bunch of color variations, sharpness adjustments, flips, transforms, etc. Voila you have 256 images of the same dog. EDIT: I noticed that this is definitely a common idea as others have already pointed out.
