Similar images tarining set generator : I want to train my machine learning (Watson visual recognition) to detect sun doodle(black and white).
The problem that I have to train at least 700 images but I have just something like 30.

I thought about a generator that takes my images and change them and create a lot of similar images using pixle games.
Do you know a generator like this? Or do you have a good idea for me?

Thanks.
