eigenimage (plural eigenimages)
 (computing) The set of eigenvectors used by a computer system in the recognition of an image (especially of a face).

1977, Harry C. Andrews, Digital image restoration, page 38:
 Various partial summations of the individual singular eigenimage matrices are included to demonstrate the cumulative effect of the individual outer products on the reconstruction of the entire image.

1999, Peter W. Hallinan, Two and ThreeDimensional Patterns of the Face, page 62:
 The five eigenimage generic model succeeds as well as the five eigenimage individual model in capturing the global shading pattern, though the geometry is of course different.

2006, Pankaj N. Topiwala, Wavelet Image and Video Compression, page 266:
 We assume that the KLT, to a first approximation, fully decorrelates the eigenimages; we further assume that the wavelet transform fully decorrelates the pixels in each eigenimage.
