In this tutorial, we are going to describe how to generate and use eigenfaces to recognize people faces.
Eigenfaces are a set of eigenvectors derived from the covariance matrix of the probability distribution of the high-dimensional vector space of possible faces of human beings. It can be used to identify a face on a picture from a person face database very quickly. In this post, we’ll not give much details on the mathematical aspects but if you are interested on those, you can look at the excellent post Face Recognition using Eigenfaces and Distance Classifiers: A Tutorial from the Onionesque Reality Blog.
