This article reviews the\nstate-of-the-art deep learning based methods for video anomaly detection and\ncategorizes them based on the type of model and criteria of detection. We also\nperform simple studies to understand the different approaches and provide the\ncriteria of evaluation for spatio-temporal anomaly detection.","url_abs":"http://arxiv.org/abs/1801.03149v2","url_pdf":"http://arxiv.org/pdf/1801.03149v2.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"an-overview-of-deep-learning-based-methods","repo_url":"https://github.com/santiagxf/ContrastiveLearning","is_official":0,"mentioned_in_paper":0,"mentioned_in_github":1,"framework":"tf","reach":{"status":"unanswered"}}],"tasks":[{"task_slug":"anomaly-detection","task_name":"Anomaly Detection"},{"task_slug":"semi-supervised-anomaly-detection","task_name":"Semi-supervised Anomaly Detection"},{"task_slug":"supervised-anomaly-detection","task_name":"Supervised Anomaly Detection"},{"task_slug":"video-anomaly-detection","task_name":"Video Anomaly Detection"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":"https://app.syntology.ai/?focus=1801.03149","mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
