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

Table 5

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

All land cover types; RGB + IR + NDVI + texture; Kappa = 0.6640		Classification result
		Paddy rice	Non-paddy rice	Producer accuracy
Ground truth class	Paddy rice	23.15	3.85	0.8574
	Non-paddy rice	9.71	54.29	0.8483
	User accuracy	0.7045	0.9338	Overall accuracy; 0.8501, std. = 0.0048
