Light field image editing by 4D patch synthesis

This paper presents a patch-based synthesis framework for lightfield image editing. The core of the proposed method builds upon a patch-based optimization approach. The main contribution of the paper is to extend the versatile patch-based image editing framework to 4D lightfield images and enable many editing applications for them. Specifically, the paper introduces a novel 4D lightfield patch consistency measure for avoiding synthesis of inconsistent patches into the edited lightfield images. Combining with a joint 4D patch search, our method is able to maintain the correlation among views and render a consistent interpretation of the scene. The proposed method offers patch-based solutions to a wide variety of lightfield image editing problems, including inpainting, retargeting and reshuffling.
