We are going to implement the algorithm described in the paper, A Neural Algorithm of Artistic Style (https://arxiv.org/abs/1508.06576) by Leon A. Gatys, Alexander S. Ecker, and Matthias Bethge. So, it would be good to read the paper first (https://arxiv.org/abs/1508.06576). This recipe will reuse a pretrained model VGG19 available online (http://www.vlfeat.org/matconvnet/models/beta16/imagenet-vgg-verydeep-19.mat), which should be downloaded locally. Our style image will be a famous painting of Van Gogh available online (https://commons.wikimedia.org/wiki/File:VanGogh-starry_night.jpg), and our content image is a picture of Marilyn Monroe downloaded from Wikipedia (https://commons.wikimedia.org/wiki/File:Marilyn_Monroe_in_1952.jpg). The content image will be repainted according to the Van Gogh style.
