Which is better OpenCV or Matlab?

Well, MATLAB is more convenient in developing and data presentation, however, OpenCV is much faster in execution. In the case of OpenCV, the speed ratio reaches more than 80 in some cases. However, OpenCV is comparatively harder to learn due to a lack of documentation and error handling codes.

Can Kotlin replace Python?

As it seems, no one of this language will replace Python, but they will rival Python in many areas and I think this is the case for Kotlin, too. The main reason is Python’s simplicity, it has an easy data model + syntax, you have mostly one way to solve problems reducing development time.
