| 摘要: |
| 运动模糊图像复原主要取决于点扩散函数（PSF）的确定。对于匀速直线和匀速旋转运动模糊图像，运动方向和模糊尺度决定了PSF，是重要参数。根据模糊图像的像素点具有高度相关的特性，采用差分和自相关等技术，精确确定模糊尺度，为图像复原提供必要参数。仿真实验验证了该方法的正确性和有效性。 |

| Abstract: |
| For uniform linear motion and uniform rotation blurred images, settling the blur function is the key point in image restoration. The motion direction and blur extent are the important parameters determining the blur function. For the pixels in blurred images have high correlation with the neighbors, the blur extent can be estimated by derivation and correlation methods. The simulation results demonstrate that the algorithm is right, effective and efficient. |
