This guide will walk you through the process of installing OpenCV on your system. OpenCV is a powerful computer vision library that can be used for a variety of applications.

System Requirements

Before you begin, make sure your system meets the following requirements:

  • Operating System: Windows, macOS, Linux
  • Processor: 64-bit
  • Memory: At least 4GB RAM

  2. Unpack the Files: Once the download is complete, unpack the files to a directory on your system.

  3. Install Dependencies: Depending on your operating system, you may need to install additional dependencies. For example, on Ubuntu, you can install them using the following command:

    sudo apt-get install build-essential cmake git libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev libavcodec-dev libavformat-dev libswscale-dev libv4l-dev v4l-utils

  4. Configure and Build: Navigate to the OpenCV directory and run the following commands:

    cd <opencv_directory>
mkdir build
cd build
cmake ..
make -j4

  5. Install OpenCV: Once the build process is complete, you can install OpenCV by running:

    sudo make install
