Video Anomaly Detection(VAD) has been traditionally tackled in two main
methodologies: the reconstruction-based approach and the prediction-based one.
As the reconstruction-based methods learn to generalize the input image, the
model merely learns an identity function and strongly causes the problem called
generalizing issue. On the other hand, since the prediction-based ones learn to
predict a future frame given several previous frames, they are less sensitive
to the generalizing issue. However, it is still uncertain if the model can
learn the …
