Paper Abstract

In the paper, we propose a novel method of arbitrarily focused image acquisition using multiple differently focused images. First, we describe our previous select-and-merge method for all-focused image acquisition. We can get god results by using this method but it's not easy to extend this method for generating arbitrarily focused images. Then, based on the assumption that depth of the scene changes stepwise, we derive a formula for reconstruction between the desired arbitrarily focused image and multiple acquired images; we can reconstruct the arbitrarily focused image by iterative use of the formula. We also introduce coarse-to- fine estimation of PSFs of the acquired images. We show we can reconstruct arbitrarily focused images for a natural scene. In other words, we can simulate virtual cameras and synthesize images focused on arbitrarily depths.
