Track/mask person, Make everything else white/black?

Is there a way to track a person and key out the backround, I know I could typically use a Luma key for this but even though my back round is mostly white there are some shots that have these pipes at the top that would not work with luma keying. I would like to get ride of the pipes. So I figured if There was some sort of plug-in that tracks the subject (the person) then you can white out everything around them that would be great.

I have the Coremelt Everything bundle so if anything from that works that would be great but I am open to ideas.

I have attached a screen shot below

Did you actually shoot in monochrome?

No, typically would be usage of a chroma-key, green or blue, for that.
key the bg, replace it with pure white, and then de-saturate your foreground/subject, aka make it b/w.

With SliceX you can create a Mask, following your subjects head and 'cover' your background holes.

But again, that should be done in colour, the low contrasts btw guys white face and white bg makes it close to impossible to track anything .....

This Is the original frame before I put the effects on

I thought Chorma keyer was used when you actually filmed with a green/blue screen?

When we filmed it was just a white backround so from what I 've read I thought you use Luma-Keyer in that scenario. I could be flat out wrong but i just wanted to clarify my circumstances .

Regardless of what I use to key out the backround. By "keying" I can get it to look more pure white behind the subject/performer which is great for getting rid of scratch marks that were on the white backdrop..but that's not the TRUE problem. The true problem is the pipes at the top of the frame. And the Keyer distinguishes the pipes to different from the backround and would never key them out properly without seriously erasing the subject/performer...from my understanding.

I have not done this technique before with SliceX I have only removed buildings and birds from shots of the sky.
I will have to look it up, figure out how to do it, and let you know how it works out for me

P.S. here is the frame in color how it was originally shot

sorry, I'm a bit lost in your workflow here …
Your main prob is the 'hole' in your background - if camera or subjects moves, SliceX comes to rescue, don't miss coremelts many tutorials @vimeo.
Done.

but concerning 'infinite white' … I don't get it why keying a white background to replace it with white???
you either…
do it practical - use a white bg, smart lighting to separate subject from bg, +1 f-stop for clipping whites - bingo.
or…
if you want to key, for whatever reasons:
use a coloured background (green, blue), and use a colour-keyer - bingo#2.

but using an antique Luma-key, by far less 'detailed' than a colour key, 255 diff. shades of grey vs 16mio diff. shades of RGB …? Replacing white by white??
Plus, your subject is a bit/lot overexposed - face same 'colour' as bg = hard to key that.

… you made it yourself more complicated than needed, I'd say :silly:

ok, academic, you just want to get rid of the ceiling installations ....

Should have shot it on green or blue. Should have been more careful with the framing. Should have used a taller set . Should plan these things so they do not need to be fixed in post. Still, stuff happens.to all of us on the most carefully staged shoots. But. Post production fixes are often more expensive, far more difficult (and they are usually obvious) than just properly shooting.
If you can mask out the junk, you're going to have a seam at the mask. It's unavoidable since you're not keying (which has its own set of issues, thank you Karsten).
