Motion Deblurring and Application from a Single Motion Blurred Image

Motion blurred image restoration technology is highly depending on the blur parameters estimation,such as direction and length.The two parameters have geometric relations with objects' movement speed.In this paper,at the same time removing the motion blur,we propose a method to estimated speed of vehicles through a single image.Due to the relative motion between the camera and a moving object during the camera exposure time,motion blur occurs in the dynamic region of the image.It provides a visual cue for the speed measurement of a moving object.So at the time of image restoration the,vehicle speed is calculated according to the imaging geometry,camera pose,and blur extent in the image.This method is mainly based on the blur pixel spreading and the property of image in the frequency domain estimating the point spread function and combined with the wiener filtering method deblurring.Thus identificate vehicles,estimates the speed,help manage traffic.Experiment shows that the method practical strong and have a good effect.
