Published through the Cornell University Library but not yet peer reviewed, the snappily-titled Bringing Impressionism to Life with Neural Style Transfer in Come Swim explores a "recently-developed technique that uses neural networks to artistically redraw an image in the style of a source style image".

Neural Style Transfer is a type of machine learning, which transforms an image into the colours and artistic techniques of another image depending on the algorithm of the computer programme.

Not following? Okay, so it's simply a case of showing an image (in this case a painting) to an algorithm, which then applies the qualities of that image to other images in real-time. Using one of her own paintings as inspiration, Stewart employed the technique in order to give certain scenes in the film the qualities of her art.
