Centroid registration difference algorithm for detecting spatial moving targets

In order to meet the needs of recognizing the targets under the moving space background by micro spacecraft target detector (MTD). According to the particular characters of the spatial background, this paper proposes an algorithm which combines the image centroid registration with the single difference method, named the Centroid Registration Difference Algorithm. In this algorithm, we labeled only the available bright sign spots and has distilled its centroid in two frames, and then used the image centroid registration to compare the two images and eliminated the same light spots between them, then the remaining bright spots in the present image were our targets. The simulation results indicate that the proposed algorithm has a low computational cost and the effect of the recognition is good.
