The application is partitioned into object tracking and video stream encoding subsystems. The real-time object tracker is able to detect and track moving objects by video images of scenes taken by stationary cameras. It is based on the block-matching algorithm. The video stream encoding involves the optimization of an international telecommunications union ITU -T H.263 baseline video encoder for quarter common intermediate format QCIF and common intermediate format CIF resolution images. The two subsystems running on two processor cores were integrated and a simple protocol was added to realize the automated video surveillance system. The experimental results show that the system is capable of detecting tracking and encoding QCIF and CIF resolution images with object movements in them in real-time. With low cycle-count low-transistor count and low-power consumption requirements the system is ideal for deployment in remote locations. Copyright 2006 Gary Wang et al.
