【摘要】 提出了一种基于小波变换与局部能量的多聚焦图像融合算法.对不同聚焦图像进行小波变换,采用局部离散度准则对各个方向上的高频系数进行融合,采用小绝对值准则对低频系数进行融合,对融合后的小波系数进行重构,这样得到高低频比例升高的融合图像.结果表明,该方法可提取出多聚焦图像中的清晰目标,生成的融合图像效果优于用一般小波变换方法生成的图像.更多还原

【Abstract】 One kind of the wavelet transformation and the local energy multi-focusing image fusion algorithm was proposed.First the wavelet transformation to the different focusing image was made,then the local energy criterion was used to carry on the fusion to each direction high frequency coefficient,the small absolute value criterion was used to carry on the fusion to the low frequency coefficient.Finally after fusing the wavelet coefficient on restructuring.The fusion image in which the high and low frequency proportion elevates was obtained.The experimental result indicated that this method may draw in the multi-focusing image the clear goal.The production fusion image effect surpasses that made by the common wavelet transform method.更多还原
