The automatic service is already popular online, with Japanese artists eager to share their impressive results.
Cleaning up rough sketches and turning faint pencil strokes into bold outlines can now be done at the click of a button, thanks to a new service developed by a research group at Waseda University Graduate School of Science and Engineering. The project, which began in autumn 2015, was announced to the world at Siggraph 2016, the world’s largest annual event in computer graphics and interactive techniques, held in California in July this year.

And while it works incredibly well at transforming plain sketches, the model simplifies coloured lines just as easily.

The service is free for anyone to enjoy, simply by uploading a file and pressing a button on their website. While it’s incredibly fast and easy to use, the maths behind the neural network-based Sketch Simplification is a complex and impressive web of details.
