This paper introduces an intelligent visual surveillance system based on TI multimedia digital signal processor (DSP) TMS320DM642, including hardware platform, software platform and algorithm realization. As the core of this system, DSP communicates with host PC via PCI bus. User can set rules via GUI software. The video input from either analog camera or IP camera can be processed by DM642 in real...
At present, vision-based illegally parked vehicles detection faces a range of issues such as narrowness of detection range, low detection precision and robustness. This paper proposed a technique for illegally parked vehicles detection. Firstly, Omni-Directional Vision Sensors (ODVS) are used to access Omni-directional images of the scene. Secondly, a method based on two backgrounds modeled by Gaussian...
For outdoor visual surveillance scenes, a novel method based on projection histogram is proposed to suppress shadow and judge pose of human. Foreground regions are firstly extracted by background subtraction method. According to the different projection features of real object and shadow, the shadow is detected and suppressed. In order to alleviate disturbances from different humanpsilas motion poses,...
We propose a visual search engine (ViSE) as a semi-automatic component in a surveillance system using networked cameras. The ViSE aims to assist the monitoring operation of huge amounts of captured video streams, which tracks and finds people in the video based on their primitive features with the interaction of a human operator. We address the issues of object detection and tracking, shadow suppression...
