removing background

you can not remove an unknown background. background remove involves trying to decide what is background and what is not! Some educated guesses can be made but only on a case by case basis. And in cases of complex backgrounds it can be impossible to achieve except by hand.

Background Removal methods are shown in IM examples, Masking, Background removal
