Cython + OpenCV and NumPy
It all depends on what your program is doing.
If you program is just stringing together large operations that are implemented in C++ then cython isn't going to help you much if at all.
If you are writing code that works directly on individual pixels then cython could be a big help.
I have a program with mainly OpenCV and NumPy, with some SciPy as well. The system needs to be a real-time system with a frame rate close to 30 fps but right now only about 10 fps. Will using Cython help speed this up? I ask because OpenCV is already written in C++ and should already be quite optimized, and NumPy, as far as I understand, is also quite optimized. So will the use of Cython help improve the processing time of my program?
