Last Updated on August 21, 2021 by admin

OpenCV is an extensive library of open-source computer pip install python viewing, machine learning, and photography. It now plays a significant role in real-time performance that is so important in today’s systems.

By using it, one can process photos and videos to identify objects, faces, or handwriting. When combined with various libraries, such as Numpuy, Python can process OpenCV analysis structures.

To identify image patterns and their various features, we use the vector space and perform mathematical functions in these elements.

Use pip install OpenCV Python

To install OpenCV, one must have Python and PIP pre-installed on their system. Check the system if it already has Python. Go to the following instructions:

Open the Command line (search cmd in Run dialog (+ R).

Now use the following command:

If Python had already installed in the device, it will generate a message with the Python version available.

To check if PIP is already installed on your system, go to the command line and execute the following command:


 mic -V

The latest versions of Python come with pre-install PIP, but older versions need to install manually. The following guide is for version 3.4 and above. If you are using an older version of Python, you can upgrade Python with the Python website.
