document: Plenoptic image editing This paper presents a new class of interactive image editing operations designed to maintain consistency between multiple images of a physical 3D scene . The distinguishing feature of these operations is that edits to any one image propagate automatically to all other images as if the -LRB- unknown -RRB- 3D scene had itself been modified . The modified scene can then be viewed interactively from any other camera viewpoint and under different scene illuminations . The approach is useful first as a power-assist that enables a user to quickly modify many images by editing just a few , and second as a means for constructing and editing image-based scene representations by manipulating a set of photographs . The approach works by extending operations like image painting , scissoring , and morphing so that they alter a scene 's plenoptic function in a physically-consistent way , thereby affecting scene appearance from all viewpoints simultaneously . A key element in realizing these operations is a new volumetric decomposition technique for reconstructing an scene 's plenoptic function from an incomplete set of camera viewpoints
