Aug 12, 2019 at 5:02 comment added Cris Luengo Are you using a least squares fit to do linear interpolation? Yes, that will be slow... Linear interpolation is a weighted addition of the four (in 2D) values.

Jul 29, 2019 at 11:02 comment added Toby Speight You're expected to show actual code from your project - not an MCVE. Changing the structure so that we're reviewing something different is off-topic for Code Review.
Jul 28, 2019 at 20:44 comment added user11536834 Out of curiosity, why is using opencv directly not a valid answer? Asking because when performance issues crop up in a language not primarily built for raw speed, seems like the usual thing to do would be delegate that stuff to a native library. Python isn't my go-to language, but if I were writing this for Lua(JIT), and found it to be unacceptably slow, I'd probably either whip something up in C or load up a suitable library (with the FFI, either way).

added a non MCVE example, a large improvement, almost all for loops removed.

Jul 27, 2019 at 0:13 comment added Lin yes. Indeed a MCVE. I have changed all function calls to inlines inside the for-loop.

Jul 26, 2019 at 8:02 comment added Toby Speight Is this your real project code? I would have expected a function (perhaps with a sample "main" program to drive it with synthetic input). What we have here is more like the MCVE I'd expect on a Stack Overflow question.
