[edit] Description

This filter equalizes total luminosity in pairs of even and odd lines.
The filter preserves all details (no smoothing or deinterlacing).

This simple filter is useful for removing of inter-line difference from captured (telecined) 8mm films (kino, movie).
The well-known Antiflicker filter (by Donald Graft) does a good job in frames luminosity equalizing, but may to leave some inter-field differences, which are revealed after restoring to progressive frames sequence (with IVTC filters).
The EquLines filter must applied after IVTC filters but before any denoising or other processing filters such as resizing.
