Abstract

Through the analysis of characteristics about background and target in visible optical image of deep outer space

the matching of image sequence at sub-pixel is realized by the method of iterative computing which is proposed to adaptive searching the pixel-mass center of fixed star and the model of characteristics which is constructed on spatial distribution.Based on image sequence matching and dividing

the arithmetic of real-time detection for dim moving target is designed by the clustering on 8-neighbour-pixel.
