摘要
基于迭代阈值法和统计模型提出了一种新的组合式分割方法 ,该方法精确地描述了天光背景的分布情况 ,既能够精确确定图像分割的最优阈值 ,有效地消除天光背景的影响 ,又可以精确地估计出天光的平均强度 。
The sky background in CCD astronomic images can be eliminated by a combination method based on iterative thresholding algorithm and statistical model for image segmentation. It can both remove the sky background and remain the characteristic of star brightness. Then the whole exact information of stars can be seen clearly.
