Image-Based Modeling and Photo Editing

Abstract We present an image-based modeling and editing system that takes a single photo as input. We represent a scene as a layered collection of depth images, where each pixel encodes both color and depth. Starting from an input image, we employ a suite of user-assisted techniques, based on a painting metaphor, to assign depths and extract layers. We introduce two speciﬁc editing operations. The ﬁrst, a “clone brushing tool,” permits the distortion-free copying of parts of a picture, by using a parameterization optimization technique. The second, a “texture-illuminance decoupling ﬁlter,” discounts the effect of illumination on uniformly textured areas, by decoupling large- and small-scale features via bilateral ﬁltering. Our system enables editing from different viewpoints, extracting and grouping of image-based objects, and modifying the shape, color, and illumination of these objects.
