This paper describes a new framework for processing images by example, called &#8220;image analogies.&#8221; The framework involves two stages: a <i>design phase</i>, in which a pair of images, with one image purported to be a &#8220;filtered&#8221; version of the other, is presented as &#8220;training data&#8221;; and an <i>application phase</i>, in which(More)
This paper proposes a new Bayesian framework for solving the matting problem, i.e. extracting a foreground element from a background image by estimating an opacity for each pixel of the foreground element. Our approach models both the foreground and background color distributions with spatially-varying sets of Gaussians, and assumes a fractional blending of(More)
We describe an interactive, computer-assisted framework for combining parts of a set of photographs into a single composite picture, a process we call "digital photomontage." Our framework makes use of two techniques primarily: graph-cut optimization, to choose good seams within the constituent images so that they can be combined as seamlessly as possible;(More)
We present a method for searching in an image database using a query image that is similar to the intended target. The query image may be a hand-drawn sketch or a (potentially low-quality) scan of the image to be retrieved. Our searching algorithm makes use of multiresolution wavelet decompositions of the query and database images. The coefficients of these(More)
This paper introduces a new type of medium, called a <italic>video texture</italic>, which has qualities somewhere between those of a photograph and a video. A video texture provides a continuous infinitely varying stream of images. While the individual frames of a video texture may be repeated from time to time, the video sequence as a whole is never(More)
We present new techniques for creating photorealistic textured 3D facial models from photographs of a human subject, and for creating smooth transitions between different facial expressions by morphing between these different models. Starting from several uncalibrated views of a human subject, we employ a user-assisted technique to recover the camera poses(More)
For a complete copy of the book, please visit the Morgan-Kaufmann website or Amazon.com. Preface Wavelets are a mathematical tool for hierarchically decomposing functions. Though rooted in approximation theory, signal processing , and physics, wavelets have also recently been applied to many problems in computer graphics. These graphics applications include(More)
Environment matting is a generalization of traditional bluescreen matting. By photographing an object in front of a sequence of structured light backdrops, a set of approximate light-transport paths through the object can be computed. The original environment matting research chose a middle ground&#8212;using a moderate number of photographs to produce(More)
This paper presents a paradigm for automatically generating complete camera specifications for capturing events in virtual 3D environments in real-time. We describe a fully implemented system, called the Virtual Cinematographer, and demonstrate its application in a virtual " party " setting. Cinematographic expertise, in the form of film idioms, is encoded(More)
