Facial recognition is a biometric solution that measures the unique characteristics of faces. To perform facial recognition, you'll need a way to uniquely represent a face.
The main idea behind any face recognition system is to break the face down into unique features, and then use those features to represent identity.
Building a robust pipeline for feature extraction is very important, as it will directly affect the performance and accuracy of our system. In 1960, Woodrow Bledsoe used a technique involving marking the coordinates of prominent features of a face. Among these features were the location of hairline, eyes, and nose.
Later, in 2005, a much robust technique was invented, Histogram of Oriented Gradients (HOG). This captured the orientation of the dense pixels in the provided image.
The most advanced technique yet, outperforming all others...
