Graphcut textures: image and video synthesis using graph cuts

Vivek Kwatra, A. Schödl, Irfan Essa, Greg Turk, A. Bobick
Computer Science
SIGGRAPH '03
1 July 2003

In this paper we introduce a new algorithm for image and video texture synthesis in which patch regions from a sample image or video are transformed and copied to the output and then stitched together along optimal seams to generate a new (and typically larger) output. Expand

Zippered polygon meshes from range images

Greg Turk, M. Levoy
Computer Science
SIGGRAPH '94
24 July 1994

We present a method for combining a collection of range images into a single polygonal mesh that completely describes an object to the extent that it is visible from the outside. Expand

Multi-level Partition of Unity Implicits

Yutaka Ohtake, A. Belyaev, M. Alexa, Greg Turk, H. Seidel

1. Briefly summarize the paper's contributions. Does it address a new problem? Does it present a new approach? Does it show new types of results?  [AS] This paper presents a new approach to… Expand

LCIS: a boundary hierarchy for detail-preserving contrast reduction

Jack Tumblin, Greg Turk
Computer Science
SIGGRAPH '99
1 July 1999

A new low curvature image simplifier (LCIS), a partial differential equation inspired by anisotropic diffusion, reduces the scene to many smooth regions that are bounded by sharp gradient discontinuities, and a single parameter K chosen for each LCIS controls region size and boundary complexity.

Image-guided streamline placement

Greg Turk, David Banks
Computer Science
SIGGRAPH '96
1 August 1996

We introduce a technique that uses an energy function to guide the placement of streamlines at a specified density. Expand

Multi-level partition of unity implicits

Yutaka Ohtake, A. Belyaev, M. Alexa, Greg Turk, H. Seidel
Computer Science
SIGGRAPH Courses
1 July 2003

We present a new shape representation, the multi-level partition of unity implicit surface, that allows us to construct surface models from very large sets of points. Expand

Re-tiling polygonal surfaces

Greg Turk
Computer Science
SIGGRAPH '92
1 July 1992

This paper presents an automatic method of creating surface models at several levels of detail from an original polygonal description of a given object that is faithful to both the geometry and the topology of the original surface. Expand

Generating textures on arbitrary surfaces using reaction-diffusion

Greg Turk
Computer Science
SIGGRAPH '91
1 July 1991

This paper describes a biologically motivated method of texture synthesis called reaction-diffusion and demonstrates how these textures can be generated in a manner that directly matches the geometry of a given surface. Expand

Shape transformation using variational implicit functions

Greg Turk, J. O'Brien
Mathematics, Computer Science
SIGGRAPH '99
1999

We present a new shape transformation method that combines these two tasks into a single step by casting this as a scattered data interpolation problem in N + 1 dimensions. Expand

Texture synthesis on surfaces

Greg Turk
Computer Science
SIGGRAPH '01
1 August 2001

In this paper we use ideas that are adapted from texture-fromsample methods to directly synthesizing texture on a polygonal surface. Expand
