DEPRECATED: This repository has been deprecated and is no longer actively maintained (build instructions no longer work either). There is a much, much better version (where you can use ANY style) at https://github.com/reiinakano/arbitrary-image-stylization-tfjs. If you're really interested in this version of fast style transfer, this code has been integrated into the ml5.js library and the TensorFlow.js version is actively maintained over there.
This repository contains an implementation of the Fast Neural Style Transfer algorithm running fully inside a browser using the Deeplearn.JS library.
Demo website: https://reiinakano.github.io/fast-style-transfer-deeplearnjs
This is an implementation of the Fast Neural Style Transfer algorithm running purely on the browser using the Deeplearn.JS library. Basically, a neural network attempts to "draw" one picture, the Content, in the style of another, the Style.
Your data and pictures here never leave your computer! In fact, this is one of the main advantages of running neural networks in your browser. Instead of sending us your data, we send you both the model and the code to run the model. These are then run by your browser.
For each available style, your browser will download a model around ~6.6MB in size. Be careful if you have limited bandwidth (mobile data users).
I know. Sorry, I'm not really a UI designer. I have about a 10 minute tolerance for tweaking HTML and CSS until I give up. The good news is, it's all open source on Github! If you want to help improve the page's design, please send a pull request! :)
To run this locally, clone the project and prepare the development environment:
$ git clone https://github.com/reiinakano/fast-style-transfer-deeplearnjs.git
$ cd fast-style-transfer-deeplearnjs
$ npm install && bower install # Install node modules and bower componentsTo interactively develop the application
$ ./scripts/watch-demo src/styletransfer-demo.ts

>> Hit CTRL-C to stop the serverThe application will be available at http://localhost:8080/src/styletransfer-demo.html and will watch for changes of typescript code.
The way Fast Neural Style Transfer works is, one has to train a new neural network for each "Style" image and upload it to the server. Training takes 4-6 hours on a relatively powerful GPU (Maxwell Titan X).
To train your own style model from scratch, please follow the instructions from this Github repository to get your own .ckpt file. You will need Python, Tensorflow, and a decent GPU.
Once you have the model.ckpt file for your style, run the following:
$ python scripts/dump_checkpoint_vars.py --output_dir=src/ckpts/my-new-style --checkpoint_file=/path/to/model.ckpt
$ python scripts/remove_optimizer_variables.py --output_dir=src/ckpts/my-new-styleIf all goes well, src/ckpts/my-new-style should contain ~6.7MB of 49 items including a manifest.json file.
Adding the style to the application is then as simple as modifying the STYLE_MAPPINGS variable in src/styletransfer-demo.ts.
If you're able to successfully achieve cool new styles, I'd be glad to add them to this demo!
