【摘要】 在处理图像的复原问题时,盲复原方法的求解难度较大.在可能的情况下,总是先估计模糊图像的点扩散函数.对匀速直线运动所引起的图像模糊,可以精确地鉴别出图像的运动方向.若把运动方向旋转到水平轴,点扩散函数的尺度鉴别就成了一维的问题.采用自定义的算子对匀速运动模糊图像进行处理,做出了鉴别曲线,根据此曲线鉴别点扩散函数的尺度.仿真结果表明,与以往的鉴别方法相比较,该鉴别方法有很强的抗噪能力.更多还原

【Abstract】 The direction of the motion that blurs the original image can be estimated accurately.if we rotate the motion blur direction to the horizontal axis,The blur scale can be identified in 1 dimension.Using a special arithmetic operator to process the rotated motion blur image.Then,calculating the autocorrelation of the blur image and pulsing the arrays of the autocorrelation image,a curve with special peaks can be gained.From this curve,we can get the relation of the scale of point spread function and the special peaks.更多还原
