Abstract

In one embodiment, a method includes generating an outputted sequence of warped images from a captured sequence of images. Using this captured sequence of images, a computing system may determine one or more three-dimensional locations of object features and a corresponding camera position for each image in the captured sequence of images. Utilizing the camera positions for each image, the computing system may determine a view path representing the perspective of a virtual camera. The computing system may identify one or more virtual camera positions for the virtual camera located on the view path, and subsequently warp one or more images from the sequence of captured images to represent the perspective of the virtual camera at each of the respective virtual camera positions. This results in a sequence of warped images that may be outputted for viewing and interaction on a client device.
