If it were a -human- painting a fake Rembrandt, no matter how perfect an imitation, it would be called "a very very good imitation of Rembrandt" and nobody would claim that they'd in any sense brought Rembrandt back to life. Calling a very good forged Rembrandt a "new Rembrandt" would be pretty silly. Calling one generated by a computer a "new Rembrandt" seems just as silly. Just because it was composed by an algorit…

We changed from the baity title to the typically more accurate subtitle.

I'm curious why I cannot get hi res scans of old masterpieces I can use as wallpaper on my monitor. Doing image searches only turns up low res versions.

I'd guess that licensing such scans for quality reproductions is a source of revenue for museums.

I can't even find hi res scans of works held by the Library of Congress.

They require you to make an account, but they have tens of thousands of public domain photographs of many of the artworks in their collection.

I feel like it's misleading of them to say that a computer painted the picture. That makes it sound like all works of Rembrandt have been fed into a Machine Learning algorithm and finally the computer spit out this piece. After having watched the YouTube video, I fell like actually the picture was more or less photoshopped together from existing Rembrandt paintings. The role of the algorithms was "only" to generate t…

I'm guessing recent progress in texture synthesis [1] and content generation [2] using deep convolutional nets made this possible. It would be interesting to see what was actually fed into the generating system. That would be a piece of art truly speaking magnitudes.

Those techniques aren't capable of generating images at high resolution that even remotely look as crisp as what was done here.

You can read on their website [1] what they did, and seems that it involved a lot of manual labour still.

Very true. Only Rembrandt could paint a "new Rembrandt". This is just a very good imitation - not that that makes it any less impressive as a technical achievement.

Earlier quoted context omitted.

They said they incorporated the height map from the original. How did they obtain them? Do museums/galleries/owners let scientists or engineers study the layers of paint of the physical paintings?

Yes they let scientists study the layers. You can create hight maps by casting light from each side of the painting and using the shadows for your hight map calculations.

Edit: this (old) tutorial shows how you can do it yourself: http://zarria.net/nrmphoto/nrmphoto.html

I think a flat bed scanner is great for creating those maps. Just scan your peace 4 times each time rotating it 90 degrees.

That looks awesome! Thanks!

Well, not entirely. Imagine a perfect replica of Rembrandt's brain connected to an artificial body, a painting produced by this machine would be a Rembrandt.

Now imagine reducing the correlation between the artificial brain and Rembrandt's brain until you reach the level of correlation to that of the machine described in the article. There will be a precise point where the paintings produced by the device will stop being Rembrandt's.

That is not to say that this machine is producing Rembrandt's. I am only saying that your reasoning is too simplistic.
