摘要
Abstract
A new method of image restoration based in Fractional Fourier Transform (FRT) domain is presented. The blurred image including higher intensity Gaussian noise and chirp noise is transformed into FRT domain. Only when the noise FRT spectrum is well estimated, the required image FRT spectrum can be well separated and return to the space domain with the inverse ransformation. As a result, we find that the method simplifies the process of restoration and the blind restoration will be obtained when we know nothing about the degradation process affected by various factors.关键词
