Multiple Feature Fusion Based on Co-Training Approach and Time Regularization for Place Classification in Wearable Video
Figure 11
Comparison of the performance of single features (BOF, CRFH), early (Eq-MKL) and late fusion (DAS) approaches, with details of Co-Training: performances of the individual inner classifiers (CO-BOF, CO-CRFH) and the final fusion (CO-DAS). Plot of the average accuracy as a function of the amount of Co-Training feedback. The performances are plotted for 1% (a) and 50% (b) of labeled data (IDOL2 dataset, random labeling). See text for more detailed explanation.
