Technologists have produced a 3D-printed painting in the style of Rembrandt

- Houshalter 11y agoThank you. A lot more information in that video than in the article. Looks like it was half human and half algorithm. Still very interesting way of making imitation paintings.
- bhrgunatha 11y agoThey 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?
- huuu 11y agoYes 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.
- huuu 11y agoEdit: this (old) tutorial shows how you can do it yourself: http://zarria.net/nrmphoto/nrmphoto.html 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.
- return0 11y agoOff-topic, but how do you guys feel when pretending to code for the camera?
- roywiggins 11y agoIf 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 algorithm doesn't make it Rembrandtier than one painted by an expert forger. Pretty cool as a technical achievement, though.
- nxzero 11y agoHuman artist would most likely inject their own take into "imitation" art, but if the computer's art was purely derived from an artist past work, it's only inspired by the artist work; this is in theory, even the code to enable this would most likely have biases that would result in artifacts in the "new" art.
- gus_massa 11y agoFrom http://www.catb.org/jargon/html/koans.html#id3141241 http://www.catb.org/jargon/html/koans.html#id3141241 In the days when Sussman was a novice, Minsky once came to him as he sat hacking at the PDP-6. “What are you doing?”, asked Minsky. “I am training a randomly wired neural net to play Tic-Tac-Toe” Sussman replied. “Why is the net wired randomly?”, asked Minsky. “I do not want it to have any preconceptions of how to play”, Sussman said. Minsky then shut his eyes. “Why do you close your eyes?”, Sussman asked his teacher. “So that the room will be empty.” At that moment, Sussman was enlightened.
- nxzero 11y agoYes, I know, and agree.

- zitterbewegung 11y agoI'm interested in how they 3d printed this picture. Also how they colored it.
- awinter-py 11y agoelephants do really good abstract impressionism as long as you tell them when to stop. http://www.getty.edu/education/teacherartexchange/archive/Nov06/0182.html http://www.getty.edu/education/teacherartexchange/archive/No... Not to say that rembrandt = abstract impressionism. Still, the humans tagging features is kind of a copout. The 'grain of salt' for these projects is to look at the variation of outputs when you tweak the model inputs. In this case it's going to be a head with oil paint texture 9 times out of 10 (and the tenth will be cecilia jimenez 'I fix'). It won't be long until a computer can 'participate' in a genre and really contribute to art. This project, while cool, isn't there yet.
- visarga 11y agoTake a look at these: * Combining Markov Random Fields and Convolutional Neural Networks for Image Synthesis (http://arxiv.org/abs/1601.04589 http://arxiv.org/abs/1601.04589) * A Neural Algorithm of Artistic Style (http://arxiv.org/abs/1508.06576 http://arxiv.org/abs/1508.06576) They do much more than photoshopping. It's actual synthesis of new images in the style of a desired painter.
- awinter-py 11y agoneural blending side-by-side on p6 of the first paper is really cool
- ma2rten 11y agoI 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 the most average / representative of his works.
- arketyp 11y agoI'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.

- Nvn 11y agoThose 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. [1] https://www.nextrembrandt.com/ https://www.nextrembrandt.com/
- howlingfantods 11y agoI used to paint old masters portraits as a hobby (including Rembrandt). I think it's a bit disingenuous to describe this as 'painting'. On top of ma2rten's criticism that it basically photoshopped previous examples to create a most representative work, I'd add that 3D printing with texture is not painting. Rembrandt, in particular, was known for painting with countless layers of semi transparent glazes to give his paintings a sense of depth and an ethereal glow. He'd also mix his pigments with bindings aside from pure linseed oil, sometimes adding chalk or glass. 3D printing the final result with none of that process makes for a very limited reproduction. Also, I'll add that I think it's very impressive, but I think they're overselling it here.

- WalterBright 11y agoI'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.
- mdturnerphys 11y agoI'd guess that licensing such scans for quality reproductions is a source of revenue for museums.
- WalterBright 11y agoI can't even find hi res scans of works held by the Library of Congress.
- Nvn 11y agoCheck out: https://www.rijksmuseum.nl/en/search?s=objecttype&p=1&ps=12&f.principalMaker.sort=Rembrandt%20Harmensz.%20van%20Rijn&ii=0 https://www.rijksmuseum.nl/en/search?s=objecttype&p=1&ps=12&... 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.
- WalterBright 11y agoThat looks awesome! Thanks!
- dc2 11y agoEverybody keep calm - the Sublime Text 2 instance used to code in the video was registered.
- Animats 11y agoIt's an impressive achievement. But compare the computer generated image[1] with a real Rembrandt of a similar subject at high resolution.[2] Compare the detail in the neck ruff. Look at the iris of the eyes. (Why do Rembrandt's people have no eyelashes?)

- sp332 11y agoI think your first link is not high-res enough. I don't know why but the website breaks the image into tiles: www.nextrembrandt.com/static/img/painting/painting_XX.jpg where interesting values for XX are 17, 18, 22, 23, 24, 28, 29, 33. (Full range is 01-40 inclusive.)
- z3t4 11y agoIt would be cool if we could upload a photo and then have it oil painted by a computer in Rembrandt style.
- anonymousDan 11y agoYes, and I imagine it would be a short step to having e.g. your portrait painted in the style of an artist of your choice for a fraction of the cost. I wonder could there be any intellectual property issues arising from this down the line?

- return0 11y agoYou mean Deep Style-style ? https://www.reddit.com/r/deepstyle/ https://www.reddit.com/r/deepstyle/
- amelius 11y agoIf it was that easy, why didn't they produce more paintings? I have the feeling that a lot of human work still went into this painting (besides writing the algorithm).
