【摘要】 周期性误差是匀速直线运动降质图像复原中普遍存在的现象,它严重影响复原图像质量。本文针对几种典型的复原方法,给出了复原图像周期性误差的定量分析,并在此基础上提出了两种分别从频率域和空间域出发的改善误差方法。实验结果表明,这两种方法对复原图像中周期性误差的消除有普遍意义。更多还原

【Abstract】 Periodic error commonly appear in restoring uniform motion blurred picture, its appearance degrade the quality of restored image heavily. In this paper, quantitative error analysis of restored image in accordance with several typical restored methods is described. Based on this analysis, two MSE improved methods respe lively from frequency domain & space-domain are given. Experiment results show that these two methods have universal significance in the removal of periodic error disturbance in restored images.更多还原
