| 摘 要： | 分析了日食对可见光云图及其时间序列的影响规律,提出利用相关分析、均值和方差分析以及线性拟合和局部增强等技术进行日食阴影区订正的动态方法。这种方法可以有效地消除阴影,尤其是日全食区域的“黑核”,较好地恢复了云图上云的纹理结构及亮度。

| Abstract: | Based on the features of an image series obtained with geostationary satellite during solar eclipse,a dynamic method including correlation analysis,statistic technique and local enhancement is suggested for eliminating the shadow caused by solar eclipse.It has been shown that the method works efficiently and,especially in the full eclipse area,the associated"black core" on the image can also be eliminated and the texture and brightness of cloud systems can be recovered. |
