采用自适应时频分块 ATFT
By in-depth research of characteristics of multi-focus image and its definition and each algorithm, a multi-focus image fusion algorithm based on adaptive partition is proposed. Because boundary areas was more partitioned, the three areas was partitioned more accurately.
通过对多聚焦图像特征的分析,以及对多聚焦图像的清晰度特征量和现有图像分块算法的深入研究,提出了一种基于自适应分块的多聚焦图像融合算法,由于对边界区域进行了逐步逼近分块处理,使多聚焦图像的清晰区域、模糊区域以及两者的边界等三个区域的划分更准确,更多地保留了源图像的边缘信息,经过对比实验验证了该算法的融合质量要优于同类算法以及离散小波融合算法。
