NettetThe Haar-like descriptor is used to detect both eyes of the face in order to enhance the face detection accuracy. The origin of the coordinate system for the facial image is chosen to be the top-left point. Two rectangular eye-search regions with the same size are extracted from each facial image at four predefined positions. NettetEdge features: These frames detect edges (simple enough). When it comes to face-detection, think of the forehead and the eyes/eyebrows. The forehead is an exposed, flat surface of the face. This allows it to reflect more light, so it is often “lighter”. Eyebrows are generally darker. Haar-like features are digital image features used in object recognition. They owe their name to their intuitive similarity with Haar wavelets and were used in the first real-time face detector. Historically, working with only image intensities (i.e., the RGB pixel values at each and every pixel of image) made the task of feature calculation computationally expensive. A publication by Papageorgiou et al. discussed working with an alternate feature set based on Haar wavelets ins… old refurbished phones
