中文摘要：
本文从图像的特性出发，将方向信息与多分辨分析相结合，提出了基于方向滤波器组的融合思想．进而考虑到人眼的视觉特性，利用对比度塔分解（CP）捕获图像的低频分量，利用方向滤波器组（DFB）获得图像的高频分量，提出了一种基于多尺度对比度塔和方向滤波器组（CPDFB）的图像融合方法，同时分析了该方法的融合机理和计算复杂度，较好地实现了复杂图像的融合．仿真实验验证了其可行性和有效性．
英文摘要：
In terms of the characteristics of images and combining the directional information with multiresolution analysis, an idea based on directional filter banks （DFB） is presented in this paper. Considering the visual features of eyes, using the contrast pyramid （CP） analysis to capture the low frequency information of images,and directional filter banks （DFB） to obtain the high frequency information of images further, an image fusion scheme based on multiseale contrast pyramid and directional filter banks （CPDFB） is given in this article. Furthermore, analyzing the mechanism and camputational complexity, fusion results can be achieved better and save the runtime greatly at the same time. The validity and efficiency are shown by experiments.
