摘要
图像在获取、处理与传输过程中,由于多种原因的影响,图像会产生一定程度的退化,其中运动模糊是导致图像退化的常见因素之一。根据运动模糊图像的特点,详细分析了运动模糊图像的退化/复原模型。在未知系统退化模型的情况下,采用Radon变换来估计匀速直线运动模糊角度和运动模糊尺度,从而确立系统的点扩展函数(SPF),然后分别用逆滤波和维纳滤波对图像进行复原,并对两种复原方法做了比较。实验表明,该方法参数估计准确,模糊图像复原效果较好。
Images are often deteriorated by many factors during the process of acquisition, processing and transmission, blurred motion is the common factors among them. According to the characteristics of motion blurred image,this paper analyzes the degradation/recovery model of the uniform linear motion blurred images in detail. When the image degradation model is unknown, Radon transform were employed to estimate the direction and length of the motion blurring,so as to establish the system of point spread function （SPF）. Then this paper separately uses wiener filtering and inverse filtering to recover blurring image and the two kinds of recovery methods were compared. Experiments show that this method could estimate parameter estimation accurately and can restore the motion blurred images effectively.
