Soft Colour Segmentation On Light Fields

Abstract

In this work we explore methods for allowing advanced colour editing on light field images to be performed. This investigation is twofold. First we look at soft colour algorithms to decompose images into colour layers and the various ways it could be applied to light field data in order to ensure spatially consistent results. Then, with the purpose of colour editing in mind, we present an object-based layer separation method so that editing a layer does not wrongly affect specific objects. We further discuss the advantages and drawbacks that light field data present over regular single-view images for this purpose. Finally we present some editing results to show that our methods allow us to obtain visually appealing images that remain consistent across all light field views and minimise the colour artefacts inherent to layer decomposition methods.
