Abstract


The technological advancement of network and multimedia leads to the rapid development of the security industry. As an important means of security industry, video surveillance, with its easy and wide reach advantages, has penetrated into many fields, and is undergoing the historical transformation from analog to digit and going towards network-oriented, intelligent and information-based. How to make effective transmission of the real-time monitoring information through the network is the main concern of the industry in general. Intelligent video surveillance, as one of the most frontier application mode, its research has drawn attention from many fields, especially from academic and industry. Under such backgroud, this thesis implements a networked video surveillance system with the function of intelligent recognition and tracking based on DirectShow technology provided by Microsoft company.DirectShow is an excellent technology for streaming media processing, and can free application developers from hardware details and make them focus on the upper logic design. It makes the application development simple and efficient. The research in this paper, on the platform of DirectShow, carried out fully needs analysis, involved deep research of key technologies and at last proposed the general system design and the detailed system design. The major project work is about the system platform building and the software UI design and realization, including single channel filter chain building, multi-channel extention, Sample Grabber filter joining, the intelligent recognition and tracking algorithm embedding and the log identification module implemention. The system fulfilled in this thesis is of great efficiency, modularization and power compared to typical surveillance system. It achieves real-time surveillance using multipath remote IP cameras and can handle issues of motion tracking and recognition as well as tracking with viewpoint shift, etc. The thesis also summarized the key points during the development. The system performance was tested and reached the requirements and further improvement advice and direction were suggested to the system.
