Experience
监控视频馈送中的异常检测
These reconstruction-based models build representations that minimize the reconstruction error of training samples from the normal distribution. Spatio-temporal predictive models consider the correlation by viewing videos as a spatiotemporal time series and learning representations that minimize the prediction error on spatiotemporal sequences. The generative models learn to generate samples from the training distribution while minimizing the reconstruction error and the distance between generated and trained distribution. Each of these methods focuses on learning prior information useful for constructing the representation for the video anomaly detection task.
