The eigenfaces technique is an efficient face feature representation method (Sirovich and Kirby 1987), which has been applied to face recognition and classification (Turk and Pentland 1991a, b).The main concept involves representing face images as low-dimensional space vectors by using a principal component analysis … WebFeb 29, 2024 · 1. As it stands, neural networks outperform the Eigenfaces approach. With this I mean that neural networks can solve a large range of problems with more accuracy. Eigenfaces are nice because they can work already with a small amount of training samples, specially compared to neural networks that are known to be data intensive.
