Abstract
Mathematical model are researched in space domain and frequency domain for motion blurred image. A new method of time part image superposition to simulate motion blurred image is proposed based on principle of motion blurred, and many high frequency sinusoidal vibration blurred images are simulated. Series of dark stripes can be found on spectrums of motion-blurred images of a vibrating object with high frequency, which is due to zero value of Bessel function. Direction and amplitude of vibration can be got by two Radon transform, so the point spread function of blurred image can be got. Experimental results show the principle of simulation is correct and the measurement method achieves good performance. Research conclusion provides a good basis for designing an effective image restoration algorithm.
