This study introduces a novel video prediction network for enhanced anomaly detection in surveillance. The method improves accuracy by integrating multi-scale appearance and motion features, outperforming existing techniques.

Area of Science:

  • Computer Vision
  • Artificial Intelligence
  • Machine Learning

Background:

  • Video prediction algorithms are crucial for anomaly detection in smart city surveillance.
  • Current methods often fail to capture spatiotemporal information due to reliance on single-scale features and lack of temporal continuity.

Purpose of the Study:

  • To propose a novel prediction network for improving anomaly detection accuracy in video surveillance.
  • To address the limitations of existing methods in capturing multi-scale appearance and temporal motion information.

Main Methods:

  • Utilized a hybrid dilated convolution (HDC) module for multi-scale appearance feature extraction.
  • Employed a deeper bidirectional convolutional long short-term memory (DB-ConvLSTM) module to retain motion continuity.
