The stars are low contrast targets  and their self-rotation will make their brightness change in cycle. Above all  the trail trace is vulnerable to the block and disturbance of other stars. Traditional one-dimensional maximum entropy thresholding algorithm is vulnerable to the noise  and the calculation of two-dimensional entropy methods is too large and takes too much time. This paper proposes an improved two-dimensional entropy threshold algorithm. We use recursion iteration method to eliminate the redundancy calculation  and reduce the size of two-dimensional histogram based on the deep sky stars characteristic  such as low contrast  fuzziness and the centralized histogram. We also combine our algorithm with the space trail trace model to forecast the star trace. Experiments results show  when the star are blocked or they turn dark  the method still can well extrapolate the star trace. Our method improves the capability of trailing the ebb and small star  and increases the precision of tracing. It is also robust to the noise  so there is a good application foreground for the method.   Influence of RE and impurity elements on the intergranular corrosion of ZA27 alloys 期刊论文  OAI收割 CHINESE JOURNAL OF CHEMICAL PHYSICS, 2004, 卷号: 17, 期号: 5, 页码: 649-651 作者:  Li GL;  Li RD   |  收藏  |  浏览/下载：18/0  |  提交时间：2021/02/02 rare earth  zinc-aluminum alloys  recursion method  intergranular corrosion   ELECTRONIC-STRUCTURE AND MAGNETISM OF FE-GE INTERFACES 期刊论文  OAI收割 Journal of Physics-Condensed Matter, 1992, 卷号: 4, 期号: 3, 页码: 799-808 D.
