Gray Matter Interactive Studios, Inc. was founded in June, 1994.
Eigenfaces is the name given to a set of eigenvectors when they are used in the computer vision problem of human face recognition .. computer vision. computer vision. face recognition. facial recognition system. recognition. Facial recognition system. The approach of using eigenfaces for recognition was developed by Sirovich and Kirby -LRB- 1987 -RRB- and used by Matthew Turk and Alex Pentland in face classification .. recognition. Facial recognition system. Alex Pentland. Alex Pentland. The eigenvectors are derived from the covariance matrix of the probability distribution over the high-dimensional vector space of face images .. covariance matrix. covariance matrix. probability distribution. probability distribution. vector space. vector space. The eigenfaces themselves form a basis set of all images used to construct the covariance matrix .. covariance matrix. covariance matrix. This produces dimension reduction by allowing the smaller set of basis images to represent the original training images .. dimension. dimension. Classification can be achieved by comparing how faces are represented by the basis set .
