Table 6

Non-PSO versus PSO error matrix for all land cover types.

All land cover types; Non-PSO Kappa = 0.5982; PSO Kappa = 0.7510		Classification result (non-PSO/PSO)
		Paddy rice	Non-paddy rice	Producer accuracy
Ground truth class	Paddy rice	21.62/23.48	5.38/3.52	0.8007/0.8696
	Non-paddy rice	10.76/6.21	53.24/57.79	0.8319/0.9030
	User accuracy	0.6677/0.7908	0.9082/0.9426	Overall accuracy; 0.8226, std. = 0.0380/overall accuracy; 0.8931, std. = 0.0048
