Recently I stumbled across a family of algorithms known as image upscaling filters. They can scale an image to 2,3,4,5 or 6x the original size while preserving the details (using pattern recognition and other techniques). I was amazed by these algorithms and how underused they are. The main area where these algorithms are used are emulators(gameboy, SNES etc). So I decided to port the best one of them (xBRZ) to Swift. So check out the project and I hope you find it useful. I will gladly accept pull requests for any bug fixes, performance optimizations or new features. I will also be making a Python and C# port of the algorithm in the near future.
