双能量摄影胸片图像的小波融合方法

A Method of Sternum Image in Double Energy Fusion Based on Wavelet Transform

根据双能量摄影胸片图像的各自特点,采用一种新的基于小波能量尺度分析算法,有效实现了基于像素级的多模图像融合。通过对同一病人双能量摄影下的胸片图像的实际应用,表明基于该方法的医学图像融合方法能有效地集中原始多源图像的优点信息,融合图像较清晰且方法简单、实用,并可用于其他图像融合处理上。

According to the properties of the sternum image in double energy fusion, a new kind of fusion method is proposed to achieve pixel level multi- image fusion based on the wavelet energy scale analysis. It is shown that the merit information of the original multi- image is concentrated effectually and the method can be employed in other image fusion due to its convenience and utility and the fusion image is very legible through the application of sternum image in double energy.
