ROC curve for 13 AUs using six different methods: AU peak frames with shape features and SVM(Peak + Shp + SVM); all frames between onset and offset with shape features and SVM (All + Shp + SVM); AU peak frames with appearance features and SVM (Peak + App + SVM); sampling one frame in every four frames between onset and offset with PCA to reduce appearance dimensionality and SVM (All + PCA + App + SVM); AU peak frames with appearance features and Cascade AdaBoost (Peak + App + Cascade Boost); DCBB with appearance features(DCBB).
