| Abstract: | 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. |
