Abstract:
1. A method for restoring a blurred and noise-corrupted image, the method comprising: receiving the blurred and corrupted image B and a spatial-domain blur-operator matrix H that describes deterministic corruption in the blurred and corrupted image; extending the blur-operator matrix H to produce a degradation matrix Ĥ by adding rows that specify particular restored-image values obtained from smooth regions of the blurred and corrupted image B; iteratively deblurring and denoising the blurred and corrupted image B to produce a restored-image pair R and {tilde over (R)}; and storing the restored-image pair R and {tilde over (R)} in a computer-readable memory for subsequent output to a user or for transmission to a restored-image-pair receiving device.
