Hello guys I’m going to write an app using OpenCV and I wonder if there is any difference in speed between the Python and C++ OpenCV versions? I heard that Python is much slower. But I know Python much better than C++.
You're right, Python itself is much slower than C++. But OpenCV is written in C++, and the Python cv2 library only uses the API to precompiled code. So there will be no significant difference in speed. However, problems begin when you use a lot of handwritten Python code.
