Introduction to Python for OpenCV 

OpenCV is a monumental open-source library pivotal for computer vision, machine learning, and image processing. It’s integral to the real-time operations essential in modern systems. Utilising OpenCV enables the analysis of images and videos to detect objects, facial features, and even handwritten text.  

When paired with libraries like Numpy, Python becomes a powerful tool for manipulating OpenCV’s array structures for in-depth analysis. We employ vector space to discern image patterns and their distinct characteristics and execute mathematical operations on these attributes.
 

Installing OpenCV on Windows using PIP 

Installing OpenCV on Windows using PIP is straightforward and involves a few simple steps. OpenCV, also known as Open Source Computer Vision Library, is an open-source machine learning and computer vision software library. It’s widely used for various applications, including facial recognition, object detection, and motion tracking. Here, we will guide you through the ways you can follow steps to install OpenCV on your Windows computer.    

Prerequisites 

Before installing OpenCV, ensure your system has Python and PIP installed. Python, a programming language used to write scripts, and PIP is a package manager that simplifies the installation of software packages in Python. 

To check if Python is installed, open the Command Prompt and type:
 

If Python is installed, the version number will be displayed. If not, you’ll need to install It first. 

To check if PIP is installed, type the following command in the Command Prompt:
 

If PIP is not installed, you must install it before proceeding. 

Step 1: Open command prompt 

Press Win + R, type cmd, and press Enter. This will open the Command Prompt, where you will type the installation commands. 

Step 2: Upgrade PIP 

It’s good practice to ensure that PIP is up-to-date. To upgrade PIP, type the following command:
 

Step 3: Install OpenCV 

Now, you’re ready to install OpenCV. Type the following command to install the main OpenCV package:
 

If you need the additional contrib modules which provide extended functionality, use:
 

Wait for the installation to complete. Depending on your internet connection and system speed, this may take a few minutes. 

Step 4: Verify installation 

To verify that OpenCV has been installed correctly, perform a version check by typing the following commands in the Python environment:
 

If OpenCV is installed correctly, the installed version will be printed. 

Installing OpenCV on Windows using PIP is a simple process that can be completed in just a few steps. With OpenCV installed, you can explore the vast possibilities of computer vision and machine learning in your Python applications. Remember to always check for the latest version of OpenCV to take advantage of new features and improvements.
