摘要
本文根据传统的加权平均法和基于塔型变换的多尺度分解方法,以均方根误差和平均误差是否为阈值的判别标准,提出了基于客观评价系数的迭代融合方法。首先将待融合的源图像进行传统方法的融合,比较融合后图像的客观评价系数与设定阈值大小,倘若小于设定阈值,则融合操作结束;若评价系数大于设定阈值,则继续进行融合,迭代进行直到融合结果的客观评价系数达到期望值。实验结果表明,该方法的融合结果相对于传统方法更加精确。
According to traditional weighted average method and multi-scale decomposition method based on pyramid transformation,this paper proposes an iterative image fusion method based on objective evaluation.First of all,the source image is fused with traditional method.Then the objective evaluation coefficient of the fusion image is compared with a pre-set threshold;if the coefficient is less than the threshold,the fusion operation is terminated,otherwise the fusion operation is continued until the evaluation coefficients of the fusion result achieve the desired values.Experiment results show that compared with traditional methods,the integration results using this method is more accurate.
