Multiple Motion Targets Detection and Tracking Based on Embedded Linux

Motion target detection and tracking is widely applied in many fields, taking great convenience for people's life and work. In this paper, a difference-image-based motion target detection and tracking algorithm which uses statistics method and fits for embedded system, is presented. Use XScale 32 bits processor PXA270, transplant the embedded Linux and Qt/Embedded as embedded graphic library, carry out this motion target detection and tracking system by adopting mmap means capture data from camera. Experiments result shows this system has a preferably capability.
