Recognition with eigenfaces
Algorithm
1.Process the image database (set of images with labels)
•Run PCA—compute eigenfaces
•Calculate the K coefficients for each image
2.Given a new image (to be recognized) x, calculate K coefficients
3.Detect if x is a face
4.

4.If it is a face, who is it?
•Find closest labeled face in database
•nearest-neighbor in K-dimensional space
