Comparison of area under ROC curve (frame-level AUC) of different methods.

Method	Avenue	Ped2	Subway Entrance	Subway Exit
ST-AE [20]	76.5	81.7	81.8	86.4
Unmasking [10]	80.6	82.2	70.6	85.7
GMFC-VAE [11]	78.6	84.9	83.7	87.4
RBM [12]	78.7	86.4	—	—
DAEs + cGAN [14]	73.6	86.1	84.1	87.3
ConvAe [7]	74.3	79.7	84.9	83.9
Conv-LSTM-AE [18]	76.4	82.9	83.3	86.4
Spatial model	78.1	83.8	84.7	90.2
Temporal model	77.8	84.0	85.0	85.4
Spatial + temporal	80.3	84.5	87.3	90.8

Higher AUC is better.
