Deep learning - neural network

[btb4198]

I have a picture of a guy's face and I had an artist draw him as an alien. How do I make a neural network that would take in the original picture and learn how to draw the picture the that artist make?

I want to make a filter, that if you can enter in any guy's face, and the program would draw is like if it was the artist.

That's interesting and novel. Deep learning neural networks learn from large numbers of examples. If you have 100,000 example pictures of people plus 100,000 examples of how the corresponding alien pictures would look, then you can use those as training data to train a neural network.

The difficulty is not in the deep learning, but the collections of the training data.

anorlunda,

I have a lot of pictures of different faces and I am going to have the artist do the same thing to them.
So I am working on building a big database.
but again what kind of neural network should I make? All the videos I have seen on the subject, seem to be about finding an object in an image.

but I am not trying to find something

That link it to a free online book. The book explains in detail how to do what you want. It illustrates using a NIST data base of more than 250,000 images of handwritten letters identified by real people.

I have a lot of pictures

I hope you really mean that. A quarter million really is a lot. If you mean a few dozen, it won't work well.

Question,

How does you think Prequel does it's cartoon me?
Do you think they have a quarter Million of face pictures, because I really did not think it would take that many. That seems excessive.
Right now I have 139 different face Pictures redrawing by the same artist.

I don't know about Prequel, but it is possible that they did it by some means other than deep learning trained neural networks.

There are already libraries that can recognize facial features. (see e.g. DeepFace) I would start there. The first thing to learn in programming is to not reinvent the wheel.

Generative adversarial network (GAN) is what you're looking for. Or cycle GAN which can be used for unpaired images (e.g. a databased of human pictures and a separate one of aliens).

The topic you can look up is image-to-image translation.

Here is a video explaining how it works.

Thanks, I am going to watch his videos on this
