It depends. If you can, just snap an image without your foreground in there. Like if it's a hand in front of a white sheet, snap a photo of just the white sheet alone, without the hand in there. If you can't do that and need to estimate the background from the actual image, then try to identify the foreground and use some algorithm to fill in those pixels with background, like use regionfill(), or fit the whole background mask to a 2-D polynomical, or use some morphological methods, etc. You forgot to attach your image(s) so I can't really offer better advice.
Here's a start for you:
See attached m-file test.m. Of course it could have been better if you would have attached your image like I requested, because I don't think that your segmentation was that great. For example the blobs I think you're interested in are surrounded by thick black lines but the two sky blue blobs are connected to other black lines that causes them to be connected and not a roundish object and thus they got removed.
