A Framework for Multiperspective Rendering [article]

J. Yu, L. McMillan
2004 Symposium on Rendering  
We present a framework for the direct rendering of multiperspective images.  ...  Our framework can easily render a broad class of multiperspective images, such as multiperspective panoramas, neocubist style renderings, and faux-animations from still-life scenes.  ...  The contributions of our multiperspective rendering framework are: • A piecewise linear approximation of any multiperspective image using a set of 8 atomic GLC camera models. • A set of rules for tiling  ...

An evaluation of 3-D scene exploration using a multiperspective image framework

Paul Rosen, Voicu Popescu
2011 The Visual Computer  
We use a flexible MPI framework that allows trading off disocclusion power for image simplicity.  ...  Multiperspective images (MPIs) show more than what is visible from a single viewpoint and are a promising approach for alleviating the problem of occlusions.  ...  Acknowledgements We would like to thank Chris Hoffmann and Jian Cui for their valuable insights and assistance in completing this project.  ...

A Curved Ray Camera for Handling Occlusions through Continuous Multiperspective Visualization

Jian Cui, Paul Rosen, Voicu Popescu, Christoph Hoffmann
2010 IEEE Transactions on Visualization and Computer Graphics  
The camera is a powerful tool that enables seamless integration of multiple perspectives for overcoming occlusions in visualization while minimizing distortions.  ...  However, the planar pinhole camera has only a single viewpoint, which limits images to parts of the scene to which there is direct line of sight.  ...  The major contribution of the framework is a formal foundation for the analysis and development of non-conventional projections.  ...

Automatic Multiperspective Images [article]

Augusto Román, Hendrik P. A. Lensch
2006 Symposium on Rendering  
Multiperspective images generated from a collection of photographs or a videostream can be used to effectively summarize long, roughly planar scenes such as city streets.  ...  By minimizing this error metric we can automatically define the picture surface and viewpoints of a multiperspective image that reduces distortion artifacts.  ...  Thanks also to Ron Yeh for help with figures and to Vaibhav Vaish, Sarah Harriman, and Dan Morris for proofreading drafts. This work is possible due to a grant  ...

Beyond Perspective – A Model-Based Approach for Camera-Based 3D-Interface Design [chapter]

Jan Wojdziak, Rainer Groh
2014 Lecture Notes in Computer Science  
In contrast, the camera model of computer graphics or rather the projection of the three-dimensional scene onto a two-dimensional image plane is often of little practical use as a tool for designing 3D  ...  During the design process of 3D interfaces, designer and software developer make a multitude of design decisions.  ...  Based on the concepts, software frameworks and applications were developed to study CMV [13] and visualization frameworks for non-photorealistic rendering [14, 15] .  ...

In this paper, we present a methodology for real-time multi-perspective rendering on polygonal graphics hardware.  ...  Multi-perspective rendering has a variety of applications; examples include lens refraction, curved mirror reflection, caustics, as well depiction and visualization.  ...  But in general, it is possible for a space pointq to project onto multiple positions; an example is shown in Figure 4 .  ...

Multiperspective Graph-Theoretic Similarity Measure

Dung D. Le, Hady W. Lauw
2018 Proceedings of the 27th ACM International Conference on Information and Knowledge Management - CIKM '18  
For instance, human subjects may generate varied, yet valid, clusterings of objects. In this work, we propose a graph-theoretic similarity measure that is natively multiperspective.  ...  When the basis for similarity is a set of objectto-object relationships, it is natural to rely on graph-theoretic measures.  ...  Framework for Multiperspective Solutions A naive solution to multiperspectivity (i.e., Problem 1) is to run SimRank (Equation 1) on each perspective's component graph G p separately.  ...
