View selection for unstructured lumigraph rendering

Frame of DV footage                                                                                   Novel view Unstructured lumigrahs are a kind of image-based representation that are particularly painless to create. They allow for the rendering of a scene from novel viewpoints using a set of photographs and a geometric approximation of the scene. Photographs are typically extracted from video sequences, using match-moving techniques to recover necessary camera parameters. We propose an authoring tool to help a user select the right pictures, or parts of pictures, to create light-weight unstructured lumigraphs that maintain rendering quality. This work was presented at the symposium on Applied Perception in Graphics and Visualization 2007. It was extended as part of our work in StratAG and pulbished in the Transactions on Applied Perception journal: A Perceptual Approach to Trimming and Tuning Unstructured Lumigraphs.
