The idea of dynamic control cutting？

Dear Sutan：

I have a question about eis， not just this article.
As we know, Too much stability will result in black region in result when crop ratio is fix.
In general, how to dynamically control the degree of smoothness to solve this case efficiently?
Thanks

First you need to define a target FOV for the stablized video. Then add additional control terms to the energy function, which gives "black margin inside FOV" a big penality. But first you need to find a good mathematical definition for it.

Very Thanks!
