Patent ID: 8649630

Claim:
A method for processing distorted image, the method comprising: a terminal converting an obtained distorted image to a corresponding spectrum domain image or a corresponding cepstrum domain image; wherein: the step of the terminal converting the distorted image to the corresponding cepstrum domain image comprises: the terminal performing Fourier transform for a distorted image g(x, y), and obtaining a spectrum domain image G(u, v) corresponding to the distorted image g(x, y); the terminal performing transformation on the G(u, v) by using a transformation formula G % (u, v)=|log(1+|G(u, v)|)| 2 ; the terminal performing a two-dimension Inverse Fourier transform for the G % (u, v) to obtain a cepstrum domain image Cep(g(x, y)) corresponding to the distorted image g(x, y); the terminal performing a distortion parameter of the distorted image based on the spectrum domain image or the cepstrum domain image; the terminal performing recovery processing for the distorted image based on the distortion parameter.
