How to Build and Install OpenCV 4.x on macOS
If you’re a computer vision enthusiast, a machine learning practitioner, or a developer looking to work with image and video processing, OpenCV is a crucial tool to have in your toolkit. OpenCV (Open Source Computer Vision Library) is an open-source computer vision and machine learning software library containing over 2500 optimized algorithms. It’s widely used for tasks ranging from simple image processing to complex computer vision applications. In this guide, we’ll walk you through the process of building and installing OpenCV 4.x on macOS, ensuring you have the latest version and can harness its full power.
Prerequisites
Before we dive into the installation process, make sure you have the following prerequisites:
1. macOS: This guide is primarily aimed at macOS users, but you can adapt the instructions for other Unix-based systems.
