Abstract:To address the difficulty of real-time hardware of moving targets detection and the complexity of the designing process, a circuit of moving targets detection of static background subtraction on FPGA based on DSP Builder is proposed. The designs include the static background subtraction, the division of threshold and the centroid getting using the modular method and parallel calculation. The results show that this design performs efficiently on moving targets detection. In addition, the algorithm could satisty the real-time requirement of embedded systems.
Keywords:DSP Builder  FPGA
