Abstract: 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.

Key words: Gabor filter, image fusion, character of high frequency
