Table 1

The comparison of the recognition rate between the 2DPCA algorithm and this algorithm under different principal components in the ORL Library (%).

Principal component	P=6	P=8	P=10	P=20	P=45
2DPCA	89.9	90.2	91.7	92.5	93.8
WT-2DPCA	90.1	90.3	91.9	92.6	93.9
The frame theory without wavelet transform 2DPCA	90.1	90.6	92.1	92.9	94.2
The algorithm in this paper	92.3	93.1	93.9	94.1	94.8
