快速、可靠的融合算法是图像融合技术实用化的关键,因此具有良好融合效果的快速融合算法的研究显得尤为重要。传统的加权多分辨率图像融合方法能够产生良好的融合效果,但是其计算复杂度却不能令人满意,为了降低算法的复杂度,基于定义的相关信号强度比,提出了一种加权多分辨率图像融合的快速算法。同传统加权多分辨率图像融合方法相比,算法具有较低的计算复杂度。实验结果表明,该算法同传统加权多分辨率图像融合方法一样,能够产生良好的融合效果。

The key of application and practicalization of image fusion technology is whether the used fusion algorithm has fast speed and high reliability or not,so the research of computationally efficient algorithms which can produce good results is very important.Conventional multiresolution image fusion methods with weighted average fusion rule exhibit high level of fused image quality,but their fusion rules represent computationally expensive solutions.To reduce their computational complexity,using the defined correlated signal intensity ratio,a computationally efficient algorithm of multiresolution image fusion with weighted average fusion rule is presented.Compared with those conventional methods,the proposed algorithm achieves a considerable improvement in real time capabilities.The experimental results show that images achieved by this efficient algorithm are of equivalent or better quality than those obtained from more complex,conventional image fusion methods.
