摘要
介绍一种在图像频域应用相关系数分析方法来识别模糊参数的方法。该方法用一系列同一类型但不同参数的模糊模型来第二次模糊图像,然后在频域中分析两次模糊图像之间的相关系数。实验结果表明,这种方法既适合于散焦模糊模型也适合于运动模糊模型的参数识别,有一定的准确性和计算上的简便性。
A practical method for estimating the blur parameters using correlation analysis is proposed. In the frequency domain the correlation between the original blurred images and the second blurred images is analyzed after blurring the original images by a series of Point Spread Functions(PSFs) with various parameters of same model. The experimental results indicate that the algorithm is suitable for the parameter recognition of both defocus and motion blur models and has higher precision and less computational cost.
