- W2008148753 abstract "It is well known that using different versions of a scene perturbed with different blurs improves the quality of the restored image compared to using a single blurred image. In this paper, we consider images perturbed with large defocus blurs. In the case where two different blurs are used, we characterize the influence of the relative diameter of both blurs on the restoration quality. We show that using two different blurs significantly increases the robustness of the restoration to a mismatch between the kernels used in designing the restoration algorithm and the actual blurs that have perturbed the image. We finally show that using three different kernels may not improve the restoration performance compared to the two-kernel approach, but still improves the robustness to kernel estimation." @default.
