摘　　要：通过对运动模糊图像进行分析,提出了对运动模糊图像两个重要参数:运动模糊角度和模糊长度估计的一种新的方法。基于频域特性利用Radon变换对模糊图像的模糊方向进行估计的改进,又根据Radon变换的性质,将投影理论引入到运动模糊长度的估计中。仿真实验证明了其估计结果的正确性且表明,该方法简单可行,较之先前提出的许多复杂的方法,该方法具有较高的精度。By analyzing the motion blurred images,proposed a new method to estimate the motion blurred direction and motion blurred length which are two important parameters in the blurred images.Based on the frequency domain characteristics of Radon transform,proposed an improved estimation method in blurred direaction,and based on the characters of Radon transformation,the projection theory was introduced into the estimating of the motion blurred length.Simulation experiment showed the estimation results of the method was correct and that the new method was simple and feasible,compared with the old and complex methods,the new method has high accuracy.
