TLDR
In this article, a virtual world representation includes models of objects that specify the locations of the objects within the virtual world, the geometries of objects, the dimensions of the object, the surface representation of objects and other relevant information.
Abstract: 
Some representative embodiments are directed to creating a 'virtual world' by processing a series of two dimensional images to generate a representation of the physical world depicted in the series of images. The virtual world representation includes models of objects that specify the locations of the objects within the virtual world, the geometries of the objects, the dimensions of the objects, the surface representation of the objects, and/or other relevant information. By developing the virtual world representation, a number of image processing effects may be applied such as generation of stereoscopic images, object insertion, object removal, object translation, and/or other object manipulation operations.

Multi-stage production pipeline system

Barry B. Sandrew, +6 more
TL;DR: In this paper, the authors present a multi-stage production pipeline system that enables a large studio workforce to work non-linearly on a film while maintaining a unified vision driven by key creative figures, allowing for more consistent, higher quality, faster, less expensive work product and more efficient project management techniques.

Method of converting 2d video to 3d video using 3d object models

Vicente Niebla, +3 more
TL;DR: In this paper, a method for converting 2D video to 3D video using 3D object models is presented, where the object models are obtained from 3D scanner data; planes, polygons, or surfaces may be fit to this data to generate a 3D model.

Method and apparatus for processing image

Seong-Hwan Kim
TL;DR: In this article, the authors proposed a method and apparatus for processing an image, in which an image is removed from the entire photographed image and synthesized with another image using distance information to a photographed object regardless of colors or patterns of the image.

Active contours without edges

Tony F. Chan, +1 more
- 01 Feb 2001 - 
TL;DR: A new model for active contours to detect objects in a given image, based on techniques of curve evolution, Mumford-Shah (1989) functional for segmentation and level sets is proposed, which can detect objects whose boundaries are not necessarily defined by the gradient.

Machine dynamic selection of one video camera/image of a scene from multiple video cameras/images of the scene in accordance with a particular perspective on the scene, an object in the scene, or an event in the scene

Ramesh Jain, +2 more
TL;DR: In this paper, the authors present a method to synthesize video images of a scene in response to a user/viewer-specified criterion relative to which criterion the user orviewer wishes to view the scene.

User-steered image segmentation paradigms: live wire and live lane

Alexandre X. Falcão, +5 more
- 01 Jul 1998 - 
TL;DR: Two paradigms for practical image segmentation in large applications are presented, referred to as live wire and live lane, and formal evaluation studies are described to compare the utility of the new methods with that of manual tracing based on speed and repeatability of tracing and on data taken from a large ongoing application.

Recognising structure in laser scanning point clouds

George Vosselman, +3 more
TL;DR: In this paper, the authors review several techniques that can be used to recognize geometric shapes or more general smooth surfaces in point clouds and present applications in industry, urban planning, water management and forestry.
