Simulation and Analysis of Vibration Blurred Images

To efficiently recover blurred image degraded by vibration, this paper proposes a way to simulate vibration blurred images and measures direction and amplitude of vibration and gets movement parameters of vibration and point spread function of blurred image. The simulation method of time part image superposition is given according to degradation model of vibration blurred images and character of integral. The direction and amplitude of vibration are measured from spectrum of blurred image by the way of two times Radon transform. Analysis results show the principle of the simulation is correct and the measurement method achieves good performance. Research conclusion provides important basis for designing an effective image restoration algorithm.
