【摘要】 该文提出了一种基于方向可调滤波器的图像融合新方法。在该方法中,采用方向可调滤波器及其Hilbert变换组成的正交滤波器组,分析两幅不同焦点图像的高频成分中的主要方向及局部方向能量,自动判别出每幅源图像中的清晰部分,并把各个清晰区域融合入结果图像中。仿真试验表明,这种算法能很好地保存图像边界及纹理信息,并具有较好的综合感观。更多还原

【Abstract】 An image fusion algorithm based on steerable filters is presented in this paper.In this method,quadrature pair that consists of a steerable filter and its Hilbert transform is used for analysing the dominant orientation and local orientation energy in the high frequency level of each image.Then the clear regions in each original image are decided automatically,and merged into the fused image.The experimental result shows that this fusion methodology performs well in preserving edge and texture information,and has a comprehensive good behavior.更多还原
