摘要

应用GHM多小波变换对CT图像按能量进行重要度分解

得出LL、LH、HL和HH.之后对最强信息子图LL和最弱信息子图HH进行强Canny边缘检测

利用检测图像内容边缘较多较细且几乎对医疗诊断无用的特点

通过对无效边缘进行删除和异或运算处理

达到隐藏病患信息的目的.算法对病患图像进行边缘修改与信息嵌入

不仅保护常规可视效果下的隐私

而且可以安全携带病患的个人已经诊断信息.

Abstract

According to different importance degrees

CT images can be distributed into LL

HL and HHby GHM multi-wavelet.The edges of LL(with the highest important degree) and HH(with the lowest important degree) are detected by strong Canny method.With many thin edges

which are useless for medical diagnosis

patientsinformation can be hid by deletion and comparison processing of invalid edges.Edges of medical images are modified in order to embed patientsinformation

so the privacy can be protected under the normal visualization and the existing diagnosis information of patients can be carried safely.
