Blind image restoration is the process of estimating both the true image an
d the blur from the degraded image, using only partial information about de
gradation sources and the imaging system. Our main interest concerns optica
l image enhancement, where the degradation often involves a convolution pro
cess. We provide a method to incorporate truncated eigenvalue and total var
iation regularization into a nonlinear recursive inverse filter (RIF) blind
deconvolution scheme first proposed by Kundur and Hatzinakos. Tests are re
ported on simulated and optical imaging problems.
