Removing a background is still a relatively labor-intensive process in the general case. You can automate it quite a bit if you take the photographs with that in mind: good lighting, contrasting and uniform background as a minimum. But in the pictures above, even a human has trouble distinguishing the mannequin from the background.
Otherwise you can offshore the work to sweat shops in Asia, the rates aren't that high and these folks are likely more trained than you, and this can be less expensive than hiring a trained photographer locally to redo the shorts properly.
