双能量减影中的匹配问题

Study of Matching Problem in Dual Energy Substraction

本文在讨论了双能量减影的基本原理后,详细地讨论了双能量减影中的图象匹配问题,为了获得较好的图象匹配特征点,采用概率统计方法对原图进行了预处理.本文提出了几种匹配方法,尤其是分段选择匹配方法具有实际应用意义,最后给出了各种实验结果.

After discussing the principle of dual energy substraction,the paper deals with the matching problem in dual energy substraction in detail. In order to get better matching features of images,the probability enhance- ment is used to process the original images.Several matching methods are presented,among these methods,the segment chosen matching is especially useful for application.Several experimental results are given.
