【Abstract】 TMS320DM6446 is a powerful multi-media processor that leverages TI’s DaVinci? technology, based on which we realized a whole body of algorithms for active vision moving object detection and tracking, as well as for H.264 video coding. Experimental results show that the algorithms achieve a high compression rate, as well as a good performance in detection and tracking precision. All the jobs are done on our system in real time for videos with CIF size.
【Key words】DaVinci; intelligent video surveillance; object detection; object tracking
