The CSIR has a strong capability in real-time image processing that has been extended to develop applications for target tracking. Computer Graphics Processing Units (GPUs) are used to accelerate image segmentation, object detection and target tracking. The Stand Alone Tracker (SAT) prototype is a high bandwidth pan-tilt-unit that uses some of these algorithms to track single targets in real-time. SAT is integrated with radar systems and consists of high-resolution visual and infrared sensors that can be pointed at targets with high precision. Future research will look at image fusion and appearance modelling for robust target tracking, as well as object detection and segmentation methods.
