| Abstract: | Based on TMS320C5416 and FPGA, a practical system for tracking of target using particle filter is presented. The original image is firstly sampled by SAA7111A, and then transmitted to DSP by Ping-Pang Method via FPGA. The gray feature is selected as the object characteristic and particle filter is used for object tracking. Fixed-point operation is used instead of floating-point operation for increasing the speed of computation. Experimental results show that the system operates well in real-time and is robust. |
