Table 7

Non-PSO versus PSO error matrix for paddy rice versus grass.

Land cover: paddy rice versus grass; Non-PSO Kappa = 0.4528; PSO Kappa = 0.7396		Classification result (non-PSO/PSO)
		Paddy rice	Grass	Producer accuracy
Ground truth class	Paddy rice	23.08/26.20	3.92/0.8	0.8548/0.9704
	Grass	3.66/2.55	5.54/6.65	0.6022/0.7228
	User accuracy	0.8631/0.9113	0.5856/0.8926	Overall accuracy; 0.7906, std. = 0.0598/overall accuracy; 0.9075, std. = 0.0073
