Abstract: Techniques related to multiview video stabilization are discussed. Such techniques may include performing single view video stabilization on a reference video stream and propagating the single view video stabilization to another video stream based on a target disparity map.

Abstract: An example system for generating light field content is described herein. The system includes a receiver to receive a plurality of images and a calibrator to intrinsically calibrate a camera. The system also includes a corrector and projector undistort the images and project the undistorted images to generate undistorted rectilinear images. An extrinsic calibrator may rectify and align the undistorted rectilinear images. Finally, the system includes a view interpolator to perform intermediate view interpolation on the rectified and aligned undistorted rectilinear images.

Abstract: An example system for generating stereoscopic light field panoramas includes a receiver to receive a plurality of synchronized images. The system also includes a calibrator and projector to calibrate the synchronized images, undistort the synchronized images, and project the undistorted images to a sphere to generate undistorted rectilinear images. The system further includes a disparity estimator to estimate a disparity between neighboring views of the undistorted rectilinear images to determine an optical flow between the undistorted rectilinear images. The system includes a view interpolator to perform in-between view interpolation on the undistorted rectilinear images based on the optical flow. The system also further includes a light field panorama generator to generate a stereoscopic light field panorama for a plurality of perspectives using concentric viewing circles.

Abstract: Techniques related to image rectification for fisheye images are discussed. Such techniques may include iteratively determining warpings for equirectangular images corresponding to the fisheye images using alternating feature mappings between neighboring ones of the equirectangular images until mean vertical disparities between the features are reduced below a threshold, and warping the equirectangular images to rectified equirectangular images.
