| 摘 要： | 研究了运动模糊图像在空间域和频域上的数学模型,根据运动图像的模糊原理,提出了时间等分运动模糊图像的仿真方法,仿真了高频振动模糊图像.理论分析指出,物体做高频谐波振动时运动模糊成像的频谱会由于Bessel函数的零点的存在而形成系列条纹,对振动模糊图像的频谱做两次Radon变换能检测出振动的方向和振幅,从而得到高频振动模糊...

| 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. |
