GPUImage is an open source iOS, macOS, and Linux framework for GPU-based image and video processing.

The GPUImage framework lets you apply GPU-accelerated filters and other effects to images, live camera video, and movies.

  • The original version of the framework was written in Objective-C, and only supported iOS and macOS.
  • The newer GPUImage 2 was rewritten in Swift and now supports Linux platforms where Swift code can be compiled, in addition to iOS and macOS.
  • The latest GPUImage 3 is written in Swift and uses Metal in place of deprecated OpenGL (ES).

A subset of the features of this framework have been ported to Android.
