Research on multi-focus image super-resolution fusion technology based on multiscale fast definition estimation

为了提高图像融合清晰度,提出了一种基于多尺度快速清晰度估计的多聚焦图像超分辨率融合技术,利用小波分解算法结合图像清晰度估计算法,实现对多聚焦图像清晰区域的分解、识别和提取,最终得到一幅各个区域都清晰的融合图像。实验结果表明,提出的技术保留了源图像中的几乎全部最清晰区域,融合后的图像清晰度比传统方法有了大幅度的提高,融合结果比较理想。

In order to improve the image fusion definition,a multi?focus image super?resolution fusion technology based onmultiscale fast definition estimation is proposed. The wavelet decomposition algorithm combining with image definition estimationalgorithm is used to decompose,recognize and extract the clear region of multi?focus image to obtain a fusion image with clearregions. The test results show that the proposed technology can reserve all clearest region in source image,and greatly improvethe fused image definition in comparison with the traditional method. The fusion result is perfect.
