### AI overview

This tutorial introduces eigenfaces for facial recognition. It outlines collecting sample face images, training a recognition algorithm, and classifying new images, then explains how grayscale images can be represented as matrices and vectors in a high-dimensional face space.

### Source excerpt

This post assumes familiarity with the terminology and notation of linear algebra, particularly inner product spaces. Fortunately, we have both a beginner's primer on linear algebra and a follow-up primer on inner products. The Quest We are on a quest to write a program which recognizes images of faces. The general algorithm should be as follows. Get a bunch of sample images of people we want to recognize. Train our recognition algorithm on those samples.
