介绍一种倒谱分析方法,使计算机能较好地识别散焦模糊参数。在频域中应用了一些调整性算法,再变换到倒谱域来分析,以得到更好的识别准确率。
This paper introduces a practical method for computer to estimate the defocus blur parameter in cepstrum area. Fourier transformation plays an intermediate role in the path to cepstrum domain. An adjustment operation in the frequency domain was suggested and then convert to the cepstrum field to increase the accuracy of recognition.
