小波变换生物医学图像融合

Biomedical image fusion based on wavelet transformation

对图像的低频部分,融合规则为灰度与加权平均结合,而高频部分则将局部区域方差比作为权值。实验证明,该方法可以保留两幅源图像的原始信息,保留了图像的细节信息。

The fusion rule for low frequency part of the biomedical images is to combine gray level with weighted average,while the high frequency part apple region variance as the weighted value.Experimental results show that the method can save the original information of two source images and the detail of the images are maintained.
