摘　　要：探索并构建了一种基于逐像素投票的快速图像融合方法。首先,通过在不同滑动窗口步长下进行相关的可视化和定量分析实验,从中确认了使用像素步长为2的滑动窗口的融合图像性能非常接近于使用像素步长为1的滑动窗口的性能。因此,在新的快速图像融合方法中采用了像素步长为2的滑动窗口,以降低总体融合计算时间。其次,采用减小源图像分辨率的方法进一步降低快速融合算法的计算复杂度。实验结果表明,在不降低融合效果的情况下,选择合适的缩放比例可以有效提高融合算法的运行速度。此外,还对由摄影设备抖动引起的图像位移数据集进行了相关实验。提出的快速融合算法具有很强的鲁棒性,并且能够有效地融合具有轻微抖动的多聚焦源图像。The thesis constructs a fast image fusion method based on pixel-wise voting is explored and construc-ted.First,the relevant visualization and quantitative analysis experiments were carried out under different step sizes of sliding window.It is confirmed from this that the fused-image performance with a 2-pixel step of sliding window is very close to that with 1-pixel step of sliding window.Therefore,the 2-pixel step of sliding-window is used in the new fast image fusion method to reduce the overall fusion computation time.Secondly,the method of reducing the source-image resolution is used to further reduce the computational complexity of the fast fusion algorithm.The experi-mental results show that,without reducing the fusion effect,choosing the appropriate scaling ratio can effectively in-crease the operation speed of the fusion algorithm.In addition,relevant experiments were also carried out on the data set with image shift caused by the jitter of the photographic equipment.The experimental results tell that the proposed fast fusion algorithm has strong robustness and can effectively fuse the original multi-focus images with slight jitter.
