1. A Collaborative Pervasive Surveillance System (COPS) based on low bit-rate video Supervised by Prof. Shueng Han Gary Chan Presented by Ho Chi Wang, Jody Tsang Yiu Wing, Wing Yiu Ching Chak, Billy

2. Overview of Presentation Background and Importance Work from Previous FYPs System Architecture System Functionalities Conclusion Quick COPS Demonstration Question and Answer Tsang Yiu Wing, Wing Ho Chi Wang, Jody Yiu Ching Chak, Billy

3. Background and Importance Problems of Existing Video Surveillance System Huge manipulation cost Intensive human involvement Location-restricted  Collaborative and Pervasive Our Group Designed system architecture Implemented core parts of COPS Tsang Yiu Wing, Wing Ho Chi Wang, Jody Yiu Ching Chak, Billy

4. Work from Previous FYPs Ho Chi Wang, Jody Tsang Yiu Wing, Wing Yiu Ching Chak, Billy Not fulfill the requirements for the COPS –Only two components Centralized Server Simple Client  Not effectively use the resources  Not achieve a collaborative system –Not optimized settings Not maintainable and flexible for extension –Code-and-Fix strategy –Highly coupled modules Lack of project management and documentation

5. System Architecture – Overview Our COPS - Distributed System Architecture was adopted –Real-time Video Streaming Server –Application-Level Multicast Server –Video Storage Server –Web-based Image Server –Dialogic Board Server –Intelligent Client Ho Chi Wang, Jody Tsang Yiu Wing, Wing Yiu Ching Chak, Billy

6. System Architecture – Pictorial View Ho Chi Wang, Jody Tsang Yiu Wing, Wing Yiu Ching Chak, Billy

7. System Architecture – Server and Client Structure Layered Model – 3 layers was introduced A set of well-defined interfaces between modules Implemented as Dynamic Link Library (DLL) Network Streaming ServerIntelligent Client Network Encoder Decoder GUICaptureIntrusion GUI Ho Chi Wang, Jody Tsang Yiu Wing, Wing Yiu Ching Chak, Billy

8. Real-time Streaming Server Multiple camera supports Video encoding – H.263+ 30 fps for QCIF 15 fps for CIF Video streaming – UDP, RTP and TCP Intrusion detection and event-driven alert service System Functionalities – Streaming Server Yiu Ching Chak, Billy Ho Chi Wang, Jody Tsang Yiu Wing, Wing

9. Client-side Real-time Monitor Video decoding – H.263+ UDP, RTP and TCP Intrusion detection alert Alarming sound Storage Server Video Playback Video sequence searching File Playback Multiple video format support H.263+, RGB, YUV System Functionalities – Intelligent Client Yiu Ching Chak, Billy Ho Chi Wang, Jody Tsang Yiu Wing, Wing

10. User Friendly Interface Multiple camera previews Detailed event log Information display – fps, bps Icon menu Intrusion detection region settings Detailed system settings System Functionalities – Graphical User Interface Yiu Ching Chak, Billy Ho Chi Wang, Jody Tsang Yiu Wing, Wing Server Client

11. Successful System Re-engineering A whole system architecture is designed The system is modulized according to functionalities Changes to each modules can be isolated Functions-rich and high performance system is developed Good Project Management and Documentations Conclusion – Major Accomplishments Tsang Yiu Wing, Wing Ho Chi Wang, Jody Yiu Ching Chak, Billy

12. Enhancing Video Encoding and Decoding Scheme H.264 – real-time video streaming with DVD quality Improving the service in the network module Support quality of service (QoS) Enhance security service of the system Conclusion – Future Extension Tsang Yiu Wing, Wing Ho Chi Wang, Jody Yiu Ching Chak, Billy
