【图像融合】基于小波变换实现CTI与MRI医学图像融合含Matlab源码（小波变换图像融合matlab实例）

1 简介

研究目的:为了对医学图像进行基于小波变换的融合.方法:首先通过学习和研究小波理论的有关知识来研究小波理论在图像融合中的应用目的和实现方法,并借助MATLAB平台,通过小波工具箱实现了图像融合,同时比较了使用这两种方法实现图像融合的效果;然后借助MATLAB中的函数,通过编程实现了图像融合算法.结果:由两幅非同源的医学图像(CT图像和MRI图像)的融合结果可见,两种方法得到的融合图像的效果一致,其对于两幅图像中同一部位相对位置偏移量小的融合效果较好,但对偏移量较大以及存在形变情况的融合则效果不好.结论:通过小波工具箱可以实现一些简单的医学图像融合,但是随着医学图像融合技术的进一步发展和医学图像的复杂度的进一步加深,尤其是对于腹部和胸部的医学图像,则要通过非刚性配准之后才能再进行融合显像,其过程更加复杂.
