TABLE 4. Atherosclerotic Carotid Video Plaque Texture Classification Evaluation Results Between the A and S Groups. SVM Models Trained and Evaluated Using 10-Fold Cross Validation, and the RBF Kernel With c=1 And Gamma=0.01.

Feat.	CC	%CC	%TP	%FP	%Pre.	%Rec.	ROC
All	80/80	100	100	0	100	100	100
SysF	64/80	80	80	20	81	80	80

A: Asymptomatic and S: Symptomatic groups of subjects. CC: Correct classification, TP: True positive, FP: False positive, Pre: Precision = TP/(TP+FP), Rec: Recall = TP/(TP+FN), ROC: Area under the ROC curve. All: All features used (1: SF-GSM_S, 2: SF-GSM_D, 3: SGLDM-Contrast_S, 4: SGLDM Contrast_D, 5: GLDS-Entropy_S, 6: GLDS-Entropy_D). SysF: Only systole features (1, 3, 5, 7), DiasF: Only diastole features (2, 4, 6, 8).
