Minimizing dead zones in panoramic images
Abstract:
Techniques to minimize problems with dead zones associated with panoramic cameras are described. A dead zone is an area about a zero degree boundary where a three hundred and sixty degree panoramic image is split so that a two-dimensional panorama can be rendered. Redirection of the zero degree boundary to a position where no object appears is described that prevents an object located in the dead zone from being split between margins of the panorama. Another technique involves reproducing one or more portions of the image that appears at one margin adjacent to an opposite margin so that an object in the dead zone that would normally be split is reproduced in whole. The described techniques may be implemented in a panoramic camera endpoint device or in a client device remote from a camera. The techniques may be applied to live video or to previously recorded video.
