基于相似变换的CT图像缺陷定位方法

Defects Location Method of CT Image Based on Similarity Transformation

摘要: 为对CT图像中的缺陷进行简单有效定位,提出一种基于相似变换的缺陷定位新方法。在提出并证明相似变换性质的基础上用该法对验证CT图像进行缺陷定位,从定位结果的分析得出基于相似变换缺陷定位方法的有效性和准确性。从不同模板定位结果的比较得出人为构建模板的可行性。

Abstract: In order to locate the defects in CT image simply and effectively,a new method base similarity transformation was put forward. The defect location of CT image is got by the method on basis of similarity transformation properties put forward and proved.The effectiveness and accuracy of the method turned out by was put forward.The defect location of CT image is go analysis on location result.The feasibility of artificial template is drawn from comparison between different location results got by different templates.
