An ontology-driven context aware framework for smart traffic monitoring
TL;DR: This paper discusses the key tasks of vision and probabilistic reasoning components that provide a feasible solution to identify the cause of traffic jam and shows effectiveness of real-time vehicle monitoring to assess congestion on road and offer user an assistive environment to operate.
Proceedings ArticleDOI
An Ontology-based Context-aware IoT Framework for Smart Surveillance
TL;DR: Continuous video stream of data captured by CCTV cameras can be processed on the fly to give real-time alerts to concerned authorities and these alerts can be disseminated using e-mail, text messaging, on-screen alerts and alarms.
Proceedings ArticleDOI
Extending MOWL for Event Representation (E-MOWL)
TL;DR: This paper proposes a new specification for representing Events using MOWL (E-MOWL), which would enhance event detection and facilitate complete semantics, besides providing scope for personalized multimedia information retrieval.
Proceedings ArticleDOI
A Novel Approach for Securing Forensic Documents Using Rectangular Region-of-Interest (RROI)
TL;DR: DCT and DWT based transform domain watermarking techniques were implemented on RROI and the performance of the two were compared on the basis of PSNR to check the robustness of the watermark.
Proceedings Article
Extending MOWL for Event Representation (E-MOWL).
TL;DR: In this paper, a new specification for representing events using MOWL (E-MOWL) is proposed, where higher-level complex events are detected based on the hierarchy of events present in the Event Ontology created using mOWL.
