Recursive propagation of correspondences with applications to the creation of virtual video

Efficiently synthesizing virtual video

“…The image plane of an arbitrary camera with origin can be obtained from by application of an appropriate projective transformation that effectively rotates the image plane from to . If we fix a scene point and consider its projections , , and onto , , and respectively, we have the central equation (8) This result was first obtained by Seitz and Dyer [5], who called the process "view morphing". Observe that the camera is described relative to and , not in reference to absolute three-dimensional (3-D) coordinates.…”

“…9(c) using . We used the algorithm suggested in [5] to obtain rectifying transformations ( , ) and let in (8). While the rendered pixels appear realistic, the eye is drawn to the limited extent of the virtual image compared to the originals, and the black regions in the virtual image plane that correspond to pixels visible in only one of the images ( , ).…”

“…These natural outdoor images come from widely separated cameras viewing a soccer game. A dense correspondence of all points that appear in both images was estimated using the correspondence graph formalism described above, and the view morphing equations (8) and (9) were used to create the virtual image in Fig. 9(c) using .…”

“…The user need only provide a small set of point matches in the first frame pair and an algorithm to segment and track moving objects in the scene. A shorter version of this work originally appeared in [8].…”

A Comprehensive Approach to Fusion for Microsensor Networks: Distributed and Hierarchical Inference, Communication, and Adaption

“…By: John Fisher (MIT), Alan Willsky (MIT), Sanjeev Kulkarni (Princeton) IT-2, RCA-1, 5 Publications: [13,1,35,14,34,12,11] Array processing problems are typically cast assuming either a single sensing modality or that fusion of different modalities occurs at the decision level. The first leads to correlation based approaches, while the second implicitly assumes some level of independence between different modalities.…”
