While testing also the bnary masks are needed for bothe the domains?

[ManuBN786]

After going through the paper and implementation, I realized that while testing on random images too we need to input the binary masks for both the domains?

Then can someone explain to me then what is the whole point of this research work?

If binary masks are needed all the time, then I can use a conventional technique like Alpha Blending or Cloning and get the job done with limited resources .

Huh !!
