Based on a comprehensive analysis of image fusion method of wavelet decomposition transform,this paper proposes region-based fusion rules of the wavelet decomposition,in which the original image is decomposed into low frequency part and high frequency part by using wavelet decomposition.For the low-frequency part,weighting coefficients is adopted,for the high-frequency part and different direction of the component,different fusion rule is used based on local energy.The experimental results are obtained from the emulation by using visible light images,infrared images and low resolution images.The feasibility of the method is verified by using an objective evaluation index.The experiments show that this method is more effective than that of pixel-based wavelet transform.
