摘　　要：为了复原模糊图像以得到可辨识的目标,分析相机与目标高速相对运动时产生的两种模糊性质,针对其退化函数难以确定的特点,提出一种基于图像插值分析的交互式分层复原方法,该方法首先对图像进行插值,以提高对低分辨率图像退化机理的分析能力,并在分析的基础上进行图像预处理。然后在图像复原的优化准则下,交互地选择出降质模型的最优参数组合,以得到两个降质函数,最后对原图像实施分层复原。对仿真图像进行实验,基本上恢复了目标图像的特征,证明该方法复原效果比较理想。In order to restore the blurred image to obtain the cognizable target, we analyzed two kinds of blur characters, which produced by the high speed relative motion between camera and target. For the question that the degraded function of whole degradation process was difficult to ascertain, we proposed a method of mutual layered restoration based on image interpolation, First, the method improves the analysis ability of low resolution images through image interpolation. And then we chose the optimal parameter combination of the two degradation functions mutually under the optimization rule of mean squared error. The layered restoration could be implemented with the two degradation functions of blurred image. We restored the image and obtained the main characters of the target image in simulation experiment. The result shows that the method is effective.
