While doing the specialization, one of the things that called my attention most was the Neural Style Transfer. So last year i did some basic research, and published a comparison between different methods to do it. One being the Gatys paper that is explained in Course 4, and some other methods, including the ones used in the Google Arts & Culture app.
If someone is interested, HERE is the link to the publication.
And just for fun, I also created a web site where anybody and upload an image and apply one of a few pre selected styles HERE, just be patient HD styles (Gatys) take several minutes to process.
Please let me know if you like them or have questions.
