this simple module detects edges and removes coloured fringes which are caused by any kind of chromatic aberration (or other issues, for that matter).
since it tries to detect edges and saturation (with the assumption that r=g=b
is "white"), it depends on a reasonably white balanced colour space, i.e. place
it after the colour module.
