Calculating row information?

Hi. I'm working on a script to automatically remove specific broken lines from broken frames (kind of like DeScratch, but more precise).

Right now, the only thing troubling me is that, I can't find any filter or function to calculate row information. I want to set a row completely white if its average luma is above a certain value, or otherwise, completely black.

For the last script, I used something like this:
But I don't find it precise nor smart.

Technically, I can do something like this:
StackVertical(Crop(0,0,0,1).ScriptClip("..."),Crop(0,1,0,1).ScriptClip("..."),Crop(0,2,0,1).ScriptClip("..."), ...)
But I don't find it elegant enough, because the video has 480 rows, not 4 or 8. Even if I achieve it with functions & recursion, I'm not sure if the speed would be OK, since StackVertical would be used 479 times.

So I'm humbly asking advanced video workers here, if there's any filter that can apply to rows, or calculate row information. Thank you.
