一种基于双边滤波器和余量去卷积的图像复原方法
摘要：
本发明公开了一种基于双边滤波器和余量去卷积的图像复原算法，(1)根据待复原图像及其已知模糊核，采用标准RL算法做高次迭代，得到含有振铃的复原图像；(2)采用双边滤波器对含有振铃的复原图像实施滤波操作，得到消除振铃后的复原图像；(3)用已知模糊核对消除振铃后的复原图像进行卷积处理，得到重模糊图像；(4)利用步骤(3)所得的重模糊图像及待复原图像采用余量去卷积得到复原图像细节，并与消除振铃后的复原图像相加得到新的含有振铃的复原图像；(5)多次重复步骤(2)～步骤(4)得到最终复原图像。本发明方法能够有效抑制迭代算法复原图像中产生的中、高频振铃，保持丰富的图像细节，得到高质量的复原图像。
摘要（英）：

The invention discloses an image restoration method based on a double-edge wave filter and margin deconvolution, comprising the following steps: (1) obtaining a restoration image with rings by adopting a standard RL algorithm to carry out higher iteration according to an image to be restored and a known fuzzy core; (2) adopting a double-edge wave filter to carry out filtering operation of the restoration image with rings to obtain the restoration image without rings; (3) carrying out the deconvolution on the restoration image without rings by the known fuzzy core to obtain a re-fuzzy image; (4) obtaining a restoration image detail by adopting the margin deconvolution by the re-fuzzy image obtained by the step (3) and the image to be restored, and adding the restoration image detail with the restoration image after eliminating ring to obtain a new restoration image containing ring; and (5) repeating the steps (2)-(4) for many times to obtain a final restoration image. The image restoration method can effectively inhibit middle and high frequency rings in the restoration image of the iterative algorithm, remain rich image details and obtain high-quality restoration images.
