| 摘 要： | 从离散直观角度分析了由匀速旋转运动引起图像模糊的机理，通过Z变换方法，建立了由匀速旋转运动引起图像模糊的退化模型和恢复模型，并给出了快速算法。将运动模型扩展到任意形式的匀速运动，并给出了数学模型。通过计算机仿真实验，验证了算法的正确性、有效性和快速性。本文推导的是理想模型，没有考虑噪声的影响。

| Abstract: | According to discrete conception, mechanism of image blur caused by uniform motion is analyzed. Mathematical models of image blur and restoration by uniform rotation motion are established by means of Z transform. Fast restoration algorithm is presented. Subsequently the motion form is extended to arbitrary uniform motion; mathematical models and the fast algorithm are given. The computer simulation results demonstrate that the algorithm is proper and effective. |
