| Abstract(in English) | This paper proposes a novel spatial-invariant filtering method for rendering focus effects without ghosting artifacts from undersampled light fields. The presented method does not require any scene analysis such as depth estimation and feature matching. First, we generate a set of images focused on multiple depths by using the conventional synthetic aperture method and treat it as a 3D image. Second we convert it to the ghost-free 3D image. This paper shows this conversion can be achieved simply by a 3D filtering in the frequency domain. The proposed filter can also produce depth-of-field effects. |
