Abstract: An interactive multi-view module identifies a plurality of media items associated with a real-world event, each of the plurality of media items comprising a video portion and an audio portion. The interactive multi-view module synchronizes the audio portions of each of the plurality of media items according to a common reference timeline, determines a relative geographic position associated with each of the plurality of media items and presents the plurality of media items in an interactive multi-view player interface based at least on the synchronized audio portions and the relative geographic positions.

Abstract: Herein is described a method of estimating dominant motion between a current frame n and another frame m of an image sequence having a plurality of frames, the method comprising generating integral projections of the images and using gradients of those projections and using differences between the projections. The input may be any sequence of image frames from an image source, such as a video camera, an IR or X-ray imagery, radar, or from a storage medium such as computer disk memory, video tape or a computer graphics generator.

Abstract: A method for determining the position of multiple cameras relative to each other includes at a processor, receiving video data from at least one video recording taken by each camera; selecting a subset of frames of each video recording, including determining relative blurriness of each frame of each video recording, selecting frames having a lowest relative blurriness, counting features points in each of the lowest relative blurriness frames, and selecting for further analysis, lowest relative blurriness frames having a highest count of feature points; and processing each selected subset of frames from each video recording to estimate the location and orientation of each camera.
