Analysis of Facial Images across Age Progression by Humans

Table 2

Face-verification accuracy results of human and a baseline algorithm [28].

Age	Gap 0–5	Gap 6–10	Gap 11–15	Gap 16+
<18	0.775 | 0.344	0.744 | 0.155	0.751 | 0.078	0.789 | 0.125
18–29	0.784 | 0.420	0.792 | 0.257	0.793 | 0.134	0.812 | 0.080
30–39	0.821 | 0.452	0.803 | 0.300	0.743 | 0.231	*
40+	0.750 | 0.800	*	*	*

Note: (1) “|’’ means “accuracy of human experiment | accuracy of PCA algorithm’’; (2) “*’’ indicates there are not enough data for evaluation. The same notations apply for other tables as well.
