Why Python is best for OpenCV?

Fast prototyping

Python is well-suited for implementing new features. Libraries like OpenCV are written in C++ and make Python have slower runtime as it will still call C/C++ libraries. This means you will have the development advantage from Python while you can have performance optimization from C++.

Does OpenCV need training?

With OpenCV 3.3, we can utilize pre-trained networks with popular deep learning frameworks. The fact that they are pre-trained implies that we don't need to spend many hours training the network — rather we can complete a forward pass and utilize the output to make a decision within our application.
