Performance of the DNN polyp detection in NBI and WLE images.

NBI image testing (Total TP = 14 Total TN = 5)
	Full color	Red	Green	Blue	Red + green
True positive (TP)	13	12	12	10	13
True negative (TN)	5	5	5	5	5
Sensitivity TP/(TP + FN) (%)	93	86	86	71	93
Specificity: TN/(TN + FP) (%)	100	100	100	100	100
Precision: TP/(TP + FP) (%)	100	100	100	100	100
Accuracy: (TP + TN)/(TP + TN + FP + FN) (%)	95	89	89	79	95
WLE image testing (Total TP = 15 Total TN = 8)
	Full color	Red	Green	Blue	Red + green
True Positive (TP)	9	9	7	6	13
True Negative (TN)	8	8	7	7	8
Sensitivity TP/(TP + FN) (%)	60	60	47	40	87
Specificity: TN/(TN + FP) (%)	100	100	87	87	100
Precision: TP/(TP + FP) (%)	100	100	87	86	100
Accuracy: (TP + TN)/(TP + TN + FP + FN) (%)	74	74	61	57	91
