To install OpenCV on Amazon Linux, you can follow these steps:

1. Start by updating the system packages using the following command: sudo yum update -y
2. Install the required development tools and dependencies by running the following command: sudo yum groupinstall -y "Development Tools" sudo yum install -y cmake gtk2-devel numpy gcc-c++ ffmpeg-devel libjpeg-turbo-devel libpng-devel libtiff-devel libdc1394-devel libv4l-devel gstreamer-plugins-base-devel.x86_64
3. Download the OpenCV source code using wget. You can check for the latest release from the OpenCV website and update the URL accordingly. For example: wget -O opencv.zip https://github.com/opencv/opencv/archive/4.5.3.zip
4. Unzip the downloaded file: unzip opencv.zip
5. Create a build directory and navigate into it: mkdir opencv-build && cd opencv-build
6. Generate the build files using cmake. Make sure to provide the correct path to the extracted OpenCV source code in the command below: cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_FFMPEG=OFF /path/to/opencv-source/
7. Compile the OpenCV library by running: make
8. Install the compiled OpenCV library: sudo make install
9. Verify the installation by importing cv2 module in Python: python -c "import cv2; print(cv2.__version__)"

If the installation is successful, it should print the version number of OpenCV.

Remember to always verify the installation and check if there are any additional dependencies or specific configuration requirements based on your use case.
