摘要
为有效实现对点扩散函数的参数辨识,提出一种基于Radon变换的运动模糊角度的辨识算法。在获得运动模糊角度之后,采用对运动模糊图像频谱图投影求和的方法,成功辨识其运动模糊长度。仿真实验结果表明:该参数辨识算法计算量小,对运动模糊方向的辨识误差不大于3°,对运动模糊长度的辨识误差不超过0.3像素,满足运动模糊图像复原系统的技术要求。
To identify the parameter identification of point spread function（ PSF）,an identification algorithm of motion blurred direction based on Radon transform is proposed. With the help of motion blurred direction,the projective summation is used in the spectrogram of motion blurred image; then,motion blurred length is obtained through this method. The experimental results show that the proposed algorithm has the small amount of calculation and that the absolute error in motion blurred direction is less than 3°and the absolute error in motion blurred length is less than 0. 2 pixels. Therefore,the proposed algorithm is suitable for application in motion blurred image restoration.
