Abstract

Pixel art was frequently employed in games of the 90s and earlier. On today's large and high-resolution displays, pixel art looks blocky. Recently, an algorithm was introduced by Johannes Kopf and Dani Lischinski to create a smooth, resolution-indepenent vector representation from pixel art (see image). However, the algorithm is far too slow for interactive use for example in a game. The goal of this project was to implement the algorithm efficiently and on the GPU, so that it can be incorporated into current game emulators (ScummVM, dosemu, ...).
