In this paper, we propose an unsupervised approach to select representative face samples (models) from raw video s and build an appearance-based face recognition system. The approach is based on representing the face manifold in a low-dimensional space using the Locally Linear Em- bedding (LLE) algorithm and then performing K-means clustering. We define the face models as the cluster cen- ters. Our strategy is motivated by the efficiency of LLE to recover meaningful low-dimensional structures hidden in complex and high dimensional data such as face im- ages. Two other well-known unsupervised learning algo- rithms (Isomap and SOM) are also considered. We compare and assess the efficiency of these different schemes on the CMU MoBo database which contains 96 face sequences of 24 subjects. The results clearly showed significant perfor- mance enhancements over traditional methods such as the PCA-based one.
