Abstract:
Imaging-guided weapon system must have the capability of real-time extraction for target feature during multi-target real-time tracking. This paper realizes a real-time extraction algorithm for target feature based on TMS320C64x DSP platform. According to the enhanced memory access characteristics of C64x DSP, the algorithm is optimized by using multi-pixel information synchronization extraction and pixel merging approach. Experimental results show that the optimized algorithm has high implementation efficiency and high real-time performance.
