摘要
介绍了对医学图像进行多分辨率、多方向分解的Contourlet变换。针对医学图像的特点,提出一种改进的中心区域能量加权平均融合规则。进行了不同Contourlet分解层次以及基于Con tourlet变换的不同融合规则的医学图像融合的仿真实验。结果表明,图像的质量有明显提高。
This paper introduced the multi-resolution,multi-orientation decomposition contourlet transform for medical images.For the characteristics of medical image,a modified central region of the energy-weighted average fusion rule is proposed.It carried out with different levels of decomposition and contourlet transform based fusion rules in different medical image fusion simulation.The results show that image quality has improved significantly.
