摘要: We propose subspace distance measures to analyze the similarity between intrapersonal face subspaces, which characterize variations images of same individual. call conventional average (AIS) because image differences often come from a large number persons. An is referred as specific (SIS) if are just one person. demonstrate that SIS varies significantly person person, and most SISs not similar AIS. Based on these observations, we introduce maximum posteriori (MAP) adaptation problem estimation, apply it Bayesian recognition algorithm. Experimental results show adaptive algorithm outperforms non-adaptive well Eigenface Fisherface methods small available.
