基于边缘的小波图像融合算法

提出一种基于边缘的小波图像融合算法,针对小波分解的不同频率域,分别对高频系数和低频系数设计不同的融合规则。采用小波系数局部模极大和定义的局部信号强度比相结合的方法融合高频系数;对低频系数采用一种基于边缘的方法,在两幅原图像中选择最有可能是边缘的点加以保留。实验结果表明:采用此融合规则得到的融合图像具有良好的融合效果。

Edge-based image fusion algorithm with wavelet transform

An edge-based image fusion algorithm with wavelet transform was proposed,the principle of choosing high frequency and low frequency coefficients were designed respectively.The wavelet coefficient local model maximum method and the defined correlated signal intensity ration was used to fuse the high frequency component,when choosing the low frequency coefficient,the method which used is based on edges of image,selecting the pixels that might on the edges possibly from original image.The experimental results show that the fusion rule of our proposed method is effec-tive.
