Abstract
A video stream may be captured, and may have a plurality of frames including at least a first frame and a second frame. Each of the frames may have a plurality of views obtained from viewpoints that are offset from each other. A source contour, associated with a source view of the first frame, may be retrieved. Camera parameters, associated with the image capture device used to capture the video stream, may also be retrieved. The camera parameters may include a first offset between the source view and a destination view of the first frame. At least the first offset may be used to project the source contour to the destination view to generate a destination contour associated with the destination view.
