A simple test case shows that effective restoration algorithms can be employed for image restoration by using a suitable preconditioner together with a regularization scheme. The filtering properties of fast wavelet transforms are investigated in order to improve: the image stored by PCG; the image restored by PCG and the regularized technique; the image restored by conjugate gradient (CG) method and the regularization technique; and the numerical performances of image restoration software tools

Abstract
A simple test case shows that effective restoration algorithms can be employed for image restoration by using a suitable preconditioner together with a regularization scheme. The filtering properties of fast wavelet transforms are investigated in order to improve: the image stored by PCG; the image restored by PCG and the regularized technique; the image restored by conjugate gradient (CG) method and the regularization technique; and the numerical performances of image restoration software toolsI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
