Feasibility of the wavelet features for identifying Fusarium head blight.

Validation		Field Truth
Wavelet Features		Healthy	Fusarium Head Blight	Sum	UA/%	OA/%	Kappa Coefficient
Six wavelet features in the whole spectral wavelength range	Healthy	31	3	34	91.2	88.7	0.775
	Fusarium head blight	5	32	37	86.5
	Sum	36	35	71
	PA/%	86.1	91.4
Four wavelet features concentrated in the range of 400–1000 nm	Healthy	29	3	32	90.6	85.9	0.719
	Fusarium head blight	7	32	39	82.1
	Sum	36	35	71
	PA/%	80.6	91.4
