The face recognition algorithm is basically the computer application that is used for tracking, detecting, identifying, or verifying the human faces simply from the image or the video that has been captured using the digital camera.

Some popular but evolving algorithms are:
  • PCA- Principal Component Analysis
  • LBPH- Local Binary Pattern Histograms
  • k-NN (nearest neighbors) algorithm
  • Eigen’s faces
  • Fisher faces
  • SIFT- Scale Invariant Feature Transform
  • SURF- Speed Up Robust Features
