Abstract

We can generate arbitrarily focused images with arbitrarily aperture shapes from a light field, which is usually captured with a specific device such as a light field camera. In contrast, we propose a method that only needs a sparse focal stack, i.e., a few differently focused images, which can be easily captured with a conventional camera, for the same purpose. Specifically, our method first reconstructs the underlying dense light field from the sparse focal stack, and then, generates arbitrarily focused images.
