Recognition rate (%) of the LDA, SVM and QDA classifiers.

Classifier	RS (Recognition rate on the small class, i.e., the set of images that are annotated)						RO (Overall Recognition Rate)
	HPP	PMP	AMP	PP	DEDP	Mean	HPP	PMP	AMP	PP	DEDP	Mean
LDA	86	82	82	87	84	84.2	83	80	84	86	88	84.2
SVM	27	19	25	67	57	39.0	91	89	91	97	95	92.6
QDA	20	23	35	38	23	27.8	85	82	83	87	86	84.6

Tests were conducted on images in stage 11–12. Recognition rates were calculated by taking the manual annotations as the ground truth.
