I use the Resynthesizer plug in but it's built into the latest versions.
Draw a marquee around a section, go to enhance and use smart remove (it may take multiple passes in sections for larger objects).
It can be done as a batch process as long as the object stays still (naturally).
If you are hoping to do this for moving frames it's probably better to isolate the background process it and then recombine it with the rototscoped foreground elements.
Otherwise you will get a odd looking Predator cloaking device effect as the altered image becomes an animated altered field.
Not Perfect but not bad for one click.
