Restoration of motion-blurred image based on Wiener filter and its application in aerial imaging system
Jinghong Liu · Optics and Precision Engineering · 2005
The mechanism of generation of motion-blurred image was given.A mathematics model of motion-blurred image was built up.In addition,A procedure for estimating Point Spread Function(PSF) of motion-blurred was provided.The aerial vehicle platform and related system were quickly moving relative to ground target during the image data collection.The image might become blurred.The motion-blurred images could be restored using restoration of image.In restoration methods,Wiener filter is less sensitive to noise than inverse filter for the restoration of motion-blurred images,however,there is a large edge-error.This paper presents the optimal window technique for the restoration of motion-blurred images.With these optimal windows,near-perfect restorations can be obtained if the images vary gradually in intensity near their edge.
