A quadrature filter pair is designed, which consists of a steerable filter and its Hilbert transform, to analyze the dominant orientation and local orientation energy in registered images.

提出了一种基于方向可调滤波器的图像消噪及融合算法,即使用方向可调滤波器及其Hilbert变换组成的正交滤波器组,分析两幅已配准源图的主要方向及局部方向能量,根据噪声点所具有的奇异性、无方向性,从而检测出图像噪声点,并运用局部中值滤波方法消噪;对于源图中的特征,采用局部方向能量作为权重进行加权融合。

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.

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。
