WebMar 30, 2024 · There are many attempts to model normality in video sequences using unsupervised learning approaches. At training time, given normal video frames as inputs, they typically extract feature representations and try to reconstruct the inputs again. The video frames of large reconstruction errors are then treated as anomalies at test time.
