Like liquify, the Extract filter is another powerful, self-contained filter that could—in a parallel universe—be its own piece of software all together. Very simply, the extract filter allows you to extract a portion of an image, just like as if you were cutting a person (or object) out of one photo with the intention of isolating it or moving it into another photograph completely.

Rather than repeat myself here however, I'd rather refer you to a post in the Photoshop blog where I walk step-by-step through using the extract filter to extract an object from its background.
