What avisynth filter increases contrast intelligently only for low contrast parts?

Hi,

I have a video with some parts being dark with low contrast, while some other parts have reasonably good contrast with bright areas.

If I use filters like Tweak to increase contrast of the low contrast regions, naturally the ones with high contrast gets washed out in the brighter spots.

I need suggestions of Avisynth filters that can intelligently increase contrast where it is needed.

Thanks!
