同时在特定条件下具有抗遮挡的能力.

Abstract

In this paper

a matching method of stochastic sign change criterion is theoretically anlayzed. It is proved that the sign change number at matching point is maximum when the overlap and geometrical distortion are negligible. At the same time

the ability of anti-overlap is discussed. Finally

a lot of simulation experiments are done on DPS-8/52 computer system with two machine part images. The theoretical analysis and experimental results show that the matching method of stochastic sign change criterion not only can correctly complete image matching under the situation of SNR<1

but also has the ability of anti-special overlap.
