Study of Image Restoration under Rotation Motion Blurring Based on Spatial Difference Technique

Based on spatial difference technique, a method of image restoration in rotation motion is presented, where the geometric transform for the degraded image and the space invariance of the blurred function are applied.Firstly, the coordinate transform of the blurred image is used.Then the image is restored by means of spatial difference restoration in rectangular coordinate system.Finally, the de-blurred image is obtained through inverse geometric transform.The simulation and the actual application are given and it is shown that the technique is effective.
