Learning Prompt-Enhanced Context Features for Weakly-Supervised Video Anomaly Detection

1 code implementation26 Jun 2023 Yujiang Pu, Xiaoyu Wu, Lulu Yang, Shengjin Wang

Additionally, we propose a Prompt-Enhanced Learning (PEL) module that integrates semantic priors using knowledge-based prompts to boost the discriminative capacity of context features while ensuring separability between anomaly sub-classes.

Locality-aware Attention Network with Discriminative Dynamics Learning for Weakly Supervised Anomaly Detection

no code implementations11 Aug 2022 Yujiang Pu, Xiaoyu Wu

Video anomaly detection is recently formulated as a multiple instance learning task under weak supervision, in which each video is treated as a bag of snippets to be determined whether contains anomalies.
