Understanding the Haar Cascade Classifier for Face Detection
The Haar Cascade Classifier is a machine learning-based approach for object detection, specifically faces. It uses a set of pre-trained classifiers, known as Haar features, to identify facial features such as eyes, nose, and mouth. The classifier is trained on a large number of positive and negative images to accurately detect faces in different scenarios.	Image Source
