通过建立运动模糊数学模型,进行了消除运动模糊的仿真实验,维纳滤波恢复运动模糊图像效果较好。在图像恢复技术中,点扩展函数(PSF)是影响图像恢复结果的关键因素,所以常常利用先验知识和后验判断方法估计PSF函数来恢复图像。实验表明在实际恢复过程中如果运动模糊图像混入了噪声,必须考虑到信噪比、噪声的自相关函数和原始图像的自相关函数对恢复后图像的影响。
Satisfactory effect of restoration of motion-blurred image can be gained through simulation experiment based on the model of fuzzy mathematics. Point-spread function (PSF) plays a key role in image restoration. As a result, prior knowledge and posteriori estimation of PSF is usually used to restore image. Experiments show that the impact of signal noise ratio, autocorrelation function (ACF) of noise and autocorrelation function of the original image must be taken into consideration when noise is accidentally mixed in the process of restoration of motion-blurred image.
