Deep Learning Face Recognition: Part 2
Before reading this, please read deep-learning-face-recognition-part-1.html for better understanding What is Face Detection? ( locate and extract faces from each image.) The ability to detect and locate human faces in a photograph. Face detection is used for various purposes but here we use it for the only extraction of faces and pass it to the next level of face recognition. (face detection is one of the steps in our pipeline) Easiest Way to detect face is applying Sliding Window Classifier, It is done in two steps: Build a face detection model using a machine learning model which can tell whether a given image is a face or not. Slide the face detector across the large image for faces. If faces are detected it will note the location of it. Popular face detection algorithms:(Accuracy of detection increase from 1 to 3) viola jones Invented by Paul Viola and Michael Jones in the early 2000s. Uses decision trees to detect faces based on light and dark areas. ...
