WebApr 11, 2024 · Face detection is a necessary step before FER can proceed. If the face is not localized, the model or feature extraction would be difficult, affecting the recognition process [26].While many face detection algorithms exist, this paper utilizes the Viola-Jones Haar Cascade Algorithm to detect the face region due to its efficiency and speed … 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…
