How to adapt the script so it detects large and small aircrafts and outline it

[YashSharmaa]

how do i edit this to detect different sized aircraft since the slice (win) is 20 and is dependent on the model that takes only 20. i basically want to input any satellite image closeup or far and want to detect aircraft in it. please help i am stuck.

I am having problem with identifying closeup aircraft images and planes with shadow beneath them.

And if you have any research paper published on this can you let me know would be much helpful.
