    This study introduces a Weakly Supervised Anomaly Localization (WSAL) method to precisely pinpoint anomalous events in videos. The approach effectively uses temporal and spatial context for accurate anomaly detection and localization.

    Area of Science:

    • Computer Vision
    • Artificial Intelligence
    • Machine Learning

    Background:

    • Video anomaly detection is challenging, especially in precisely localizing events temporally.
    • Existing methods often struggle with accurate temporal localization of anomalies within video sequences.

    Purpose of the Study:

    • To propose a Weakly Supervised Anomaly Localization (WSAL) method for accurate temporal localization of anomalous segments.
    • To develop a model that effectively utilizes both temporal and spatial context for anomaly detection.

    Main Methods:

    • A high-order context encoding model is proposed to extract semantic representations and measure dynamic variations.
    • Spatial context information is utilized by deriving immediate semantics from segment representations.
    • An enhancement strategy is introduced to mitigate noise and lack of localization guidance.
