This project is a collection of multiple image filters packed together (mostly upscalers), written in C# .NET 7. The goal is more like getting each possible available rescaling algorithm into the library.
This project is based on the work of Hawkynt, initial project available here.
The project was optimized, modernized, ported to .NET 7 and split into 3 different C# Projects : Library of all filters and upscalers, UI and CLI. A new GUI was made in WPF in modern fluent windows 11 style using WPF-UI Library
Running all 129 Filters on a 128x128 image, on a 4x Upscale when it's available gives -60% of time reduction and -82% of memory gain.
