What is it?

GPUPixel is a C++11 library for applying real-time filters to images and video on the GPU. It is built on OpenGL/ES, so it can run on any platform that supports that API, and the project lists iOS, Android, Mac, Windows, and Linux as supported targets.

The library includes beauty filters and face-related effects such as face detection, landmarks, and face thinning, which makes it suited to live video and camera pipelines. Its filters are designed to run with low overhead, and the project is kept small in footprint.

The project provides documentation covering building from source, running demos, and integrating the library into an application.
