| 摘 要： | 在运动模糊图像盲复原的过程中,对点扩散函数(PSF)进行准确识别具有非常重要的意义.当识别出运动模糊方向后,二维PSF的识别问题就可以转化成一维PSF的识别,进而提出用一阶差分自相关的方法识别运动模糊尺度.给出了差分自相关方法用于尺度识别的理论分析,重点研究和推证了在该方法下噪声对模糊尺度识别的影响,提出了改进的差分自...

| Abstract: | It was important to identify Point Spread Function(PSF) accurately in blind motion-blurred image restoration.When we knew motion-blurred direction,the two-dimensional PSF problem could be transformed into one-dimensional problem.We used the first order difference auto-correlation method to identify motion-blurred size.This method was proved feasibly in theory.Then we researched and deduced the influence of noise particularly.In order to tackle the noise problem,the improved method was put forward.Experiment... |
