Is it possible to chromakey by using movement detection?

    Hello everyone,
    I would like to ask for help... I want to know if this is even possible..
    the setup-> 1 camera capturing(or recording as .jxs) a hallway feeding the capture to a patch-
    What I want to achieve- > I want to have 1 or various images of for example "an ocean" and I want to place the people that are walking on the hallway in the ocean (as if instead of the hallway they are walking on the ocean).
    in other words ... Chromakey out the hallway. but since the hallway is not a greenscreen and there are many colors and columns
    here is my question.....
    My main question-> is there a way to achieve chromakeying by using a camera vision library>? like cv.jit. or by using absdifference and layers? it makes some sense that it could be possible..
    basically I want to chromakey out movement; since the people are walking ( but I don't want them to be shadows but rather their real camera image. )
    what do think>?
    thanks for the help
