| Abstract: | Based on TI DSP-TMS320C5416 and FPGA, a new system for tracking of target on Histogram back-projection is presented. The original data are firstly filtered using median filter with 33 windows, then, transmitted to DSP by Ping-Pang Method. The histogram is selected as the object characteristic, and is compared with histogram back-projection for object tracking. The fixed pointer operation is used for fast computing velocity, instead of the floating pointer operation. The result of some experiments has shown that the tracking system is real-time and robust. |
| Keywords: | real-time tracking median filter histogram back-projection |
