Patch-Based Principal Component Analysis for Face Recognition

Table 5

Differences (with respect to 2DPCA) in the identifying results with different size of patches and “concatenating” strategy.

Patch size (pixel)	Accuracy (%)			Number of more identified images	Number of images failed to be identified
	91.0	0	7	42, 133	195
	91.0	0	2	200	NA
	91.0	4	0	60, 133	198
	91.0	2	2	42, 200	152
