摘　　要：利用全局搜索策略,设计适用于图像融合的最佳Gabor滤波器组,并提出了一种基于局部Gabor能量的多聚焦图像融合方法:通过利用最佳Gabor滤波器组对局部图像进行滤波,从而提取出该局部图像的Gabor能量,比较对应局部图像的Gabor能量,以挑选出其中清晰的像素并进行一致性检验,重构图像。本方法真正保留了原始的清晰图像,实现了高精度融合。通过实验,证明了该方法对于多聚焦图像的融合具有很好的效果,明显提高了运行效率。This paper proposed a method for multi-focus image fusion based on localized Gabor energy,designed the best Gabor filter banks for image fusion by the global search strategy. Using the best Gabor filter banks filter localized image for extracting Gaborenergy of localized image. Compared with the Gabor energy of localized image was in order to pick out the clear pixels of image and to verify the consistency, finally reconstructed image . This method reserved the original images to achieve high-precision integration. Experiments show that the method for multi-focus image fusion has good results and significantly improve the operational efficiency.
