Real-time motion detection of crowds in video signals
A real-time motion detection system consisting of two PCI bus plug and play cards has been developed. The PCI bus is employed as a video bus to transfer digitised video information to the motion estimation board. The motion vectors are continuously delivered to the host via the PCI bus in a DMA transfer mode. The process was developed under the Windows 95 operating system and it was tested with a number of test video sequences. This system is to be implemented as part of a crowd monitoring system.
