Apr 03, 2018 Haar cascades . OpenCV provides us with pre-trained classifiers that are ready to be used for face detection. The Haar Classifier is a machine learning based approach, an algorithm created by Paul Viola and Michael Jones; which (as mentioned before) are trained from many many positive images (with faces) and negatives images (without faces)

Dec 23, 2020 Haar Cascade Detection is one of the oldest yet powerful face detection algorithms invented. It has been there since long, long before Deep Learning became famous. Haar Features were not only used to detect faces, but also for eyes, lips, license number plates etc. The models are stored on GitHub, and we can access them with OpenCV methods

Apr 05, 2021 This update worked because the minNeighbors parameter is designed to help control false-positive detections.. When applying face detection, Haar cascades are sliding a window from left-to-right and top-to-bottom across the image, computing integral images along the way.. When a Haar cascade thinks a face is in a region, it will return a higher confidence score
