A fast correlation matching algorithm for opto-electronic tracking

The purpose of the paper is to provide a fast speed multiplying correlation algorithm which is realized by using TMS32020 high speed signal processor. The method adopts the square enhancement, coarse-fine searching and adaptive threshold technique to remove the unmatched points and improve matching accuracy. The results of the computer simulation shows that, under the condition of low SNR, the algorithm is especially useful.
