Abstract
Disclosed is a method and apparatus for multi-frame prediction error-based video anomaly detection. The disclosed apparatus for multi-frame prediction error-based video anomaly detection includes a multi-frame predictor configured to predict a current frame and adjacent frames using a prediction model; a multi-frame prediction error obtainer configured to obtain a multi-frame prediction error by obtaining a prediction error of the current frame and prediction errors of the adjacent frames that each prediction error is a difference between a predicted frame and a real frame and by adding the prediction error of the current frame and the prediction errors of the adjacent frames; and an anomaly score evaluator configured to evaluate an anomaly score based on the obtained multi-frame prediction error of the current frame.
