15 Mar Install OpenCV

This lesson is about setting up OpenCV on your computer. You’ll learn how to use pip (a tool for installing Python libraries) to install OpenCV so you can start coding.

Here’s a simple workflow for installing and OpenCV in Python:

1. Install Python and Pip
2. Install OpenCV: Use pip install opencv-python to install the library.
3. Import OpenCV: Add import cv2 at the top of your Python script.
4. Load an Image: Use cv2.imread() to load an image from a file.
5. Process the Image: Use OpenCV functions to modify or analyze the image.
6. Display the Image: Use cv2.imshow() to display the image in a window.
7. Save the Image: Use cv2.imwrite() to save the processed image to a file.

As an alternative, you can also install OpenCV on an IDE i.e. PyCharm Community Edition, which is free and open source. Learn to install PyCharm and any library, like OpenCV, SciPy, etc., on it.

Note: In this tutorial, we will create OpenCV programs on PyCharm.
