A Novel Approach to Developing a Supervised Spatial Decision Support System for Image Classification: A Study of Paddy Rice Investigation

Table 4

Error matrix for all land cover types and 4 spectral bands + NDVI (data is obtained by averaging 20 trials of calculation).

All land cover types; RGB + IR + NDVI; Kappa = 0.6238		Classification result
		Paddy rice	Non-paddy rice	Producer accuracy
Ground truth class	Paddy rice	22.05	4.95	0.8167
	Non-paddy rice	10.13	53.87	0.8417
	User accuracy	0.6852	0.9158	Overall accuracy; 0.8343, std. = 0.0052
