| 摘 要： | 提出一种基于小波多尺度分辨的多模医学图像融合算法,将待融合的图像进行小波多尺度分解,在特征域上根据图像多尺度分辨的特征实施不同权重的加权融合计算,实施逆变换完成图像重建,得到融合图像.并对人脑的MRI-PET图像进行了融合,实验结果表明该方法能有效地将解剖信息和功能信息融合在一起,并保留原始图像的解剖结构特征.

| Abstract: | In this paper, a multi-modality medical image fusion algorithm has been studied using the wavelet multiresolution analysis, The method is implemented based on the multiresolution characteristic of the coefficient derived from a daubechies wavelet multiresolution decomposition. Examples are presented here to demonstrate the efficiency of the technique on a fusion of brain MRI-T1 and PET images. |
