The video tutorial guides viewers through creating a face detection function using Python and the CV2 library. It starts with an introduction to face detection, followed by detailed steps to create a function that reads an image, converts it to grayscale, and uses a cascade classifier for detection. The tutorial also covers handling cases where no face is detected, testing the function with various images, and finalizing the function for repeated use. The video emphasizes error handling and efficient coding practices.
