I aim to start opencv little by little but first I need to decide which API of OpenCV is more useful. I predict that Python implementation is shorter but running time will be more dense and slow compared to the native C++ implementations. Is there any know can comment about performance and coding differences between these two perspectives?
Why choose?
If you know both Python and C++, use Python for research using Jupyter Notebooks and then use C++ for implementation.
The Python stack of Jupyter, OpenCV (cv2) and Numpy provide for fast prototyping.
Porting the code to C++ is usually quite straight-forward.
Does performance differ between Python or C++ coding of OpenCV?
