> Have you explored way how to handle borders?

You mean the outmost pixels, where the calculation is slightly inaccurate?
Or the greenscreen spilling into the object because of light reflections?

The first could be addressed by adjusting the value for the 
out-of-bounds pixels.

The later is harder to fix, and maybe even needs another filter for 
spill reduction which filters out the greenscreen color.

You can already get quite good results by playing with the similarity 
and blend values, eliminating most of the spill.
