一种基于Gabor滤波的不同聚焦图像融合方法

A Multi-Focus Image Fusion Method Based on Gabor Filter

提出了一种基于Gabor滤波对不同聚焦图像融合的方法。通过取不同方向的 Gabor滤波器对待融合的图像进行多方向滤波,从而提取出不同方向的高频能量,再通过比较高频能量大小来判断属于清晰还是模糊像素,以此达到融合不同聚焦图像的目的。实验表明这种方法简单有效,给出了图像融合的实验结果,并与小波变换和简单取平均融合结果进行了比较。

This paper proposes a new method based on Gabor filter for multi-focus image fusion. Using Gabor filters to filter original images in various orientations for extracting energies of high frequency in different orientations. Compare these energies to judge whether the pixel is focused, then generate the fused image. Computer simulation results illustrate that this method is simple and available. Also the test results are compard with those of other methods such as wavelet transform and direct average fusion.
