摘　　要：研究了具有深度运动模糊效果的图像的复原算法.采用对运动模糊图像的傅里叶频谱进行Radon变换来估计运动模糊方向,在此方向上计算运动模糊图像的自相关来估计运动模糊长度,再以运动模糊方向和运动模糊长度为参量结合超分辨力图像复原处理算法对比较严重的运动模糊图像进行复原.结果表明,该综合性算法能够较为精确地估算出运动模糊图像的模糊参量并取得较好的复原效果.A restoration methods of deep motion-blurred images was analyzed. Using Radon transform of the spectrum of motion blurred image, the angle of motion was estimated and the blur extent was computed by autoeorrelation of blurred image along this angle. More details of the image could be restored by superresolution arithmetic which took the angle and extent as parameters necessarily. The experiments results show that the synthesis method above can estimate the blur parameters accurately and the results are satisfied.
