HELP: How can i modify this code to do Fore-/Back-ground Segmentation (DAVIS 2016)

Hi, how nice work you have done!

Your model is designed for segmenting multi-object in the scene and achieve nice performance compared with SOTAs. But if I have the only object, what problem should I pay attention to in your project?

Look forward to your reply! Nice day!

And what's a difference between RSIS and RSISMask? Similarly, what's the difference between ConvLSTMCell and ConvLSTMCellMask? thank your kindness reply! @
