Paper Abstract

Because of the presence of noise in blurred images, an image restoration algorithm must constrain the solution to achieve stable restoration results. Such constraints are often introduced by biasing the restoration toward the minimizer of a given functional. However, a proper choice of the degree of bias is critical to the success of this approach. Generally, the appropriate bias cannot be chosen a priori and must be estimated from the blurred and noisy image. Cross-validation is introduced as a method for estimating the optimal degree of bias for a general form of the constraint functional. Results show that this constraint is capable of improving restoration results beyond the capabilities of the traditional Tikhonov constraint.
