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.

▼ The group demonstrated the results of their sketch simplification model on Twitter with this before-and-after image at the beginning of September.

▼ They followed up with another impressive example the next day.

With the online service available for public use, eager artists around the country were quick to trial the system, sharing their results on Twitter.

▼ The service handles simple sketches as well as more complex works.

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

▼ Even more impressive results can be seen when ASCII artworks are processed!

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. To read all about the model and how it works, check out their brilliant research paper in English online.
