Abstract

The blind image restoration method based on equivalent power spectrum is especially suitable to the restoration with the point spread functions (PSFs) of random characters. The problem is to identify the power spectrum of the original image in the filter transfer function expression. In this paper, a recognition method for the power spectrum of an ideal image was proposed through exploring a spectrum of the degraded image. This method is simpler and more practical than the other methods of identifying PSF parameters, and it is applicable to both cases with and without frequency domain zero-crossings in the observed image. In this paper we discuss the case with zero-crossings.
