Unpurple

Unpurple is a tool for removing purple fringes (axial chromatic aberration) from digital photos using a heuristic of my own.

Currently there is an OCaml implementation which produces a standalone executable with a simple command-line interface. It is fast enough (~ one second per megapixel) but doesn't preserve Exif data and the JPEG compression factor is fixed at 75%.

I would like to make a Gimp extension script or plugin for everyone to use.

Examples

To do

  • implement this algorithm as a Gimp script or plugin
