Table 2

Comparison of abnormal region detection methods for the leaf database (DR: detection rate, FAR: false alarm rate, Proposed 1: spectral analysis, Proposed 2: spectral + spatial analysis).

Method	DR (%)	FAR (%)	Number of bands	Detection time (s)
PCA [6]	71.6	45.8	10	6.03
Profile [13]	73.5	45.2	1040	55.53
Proposed 1	100.0	0.0008	9	0.93
Proposed 2	100.0	0.0	4	0.66
