1. A method comprising:

  • determining, via an image processing module of a computing device for a two-dimensional (2D) view of a video presentation, an optical flow for at least one frame of the 2D view, wherein the optical flow is a representation of an apparent motion of object brightness patterns in a visual plane caused by relative motion between an observer of the 2D view and objects of the 2D view;

    estimating, by the image processing module and based on the determined optical flow, global motion for the at least one frame;

    adjusting, by the image processing module, the optical flow based on the estimated global motion to create a global motion-adjusted optical flow for the at least one frame; and

    generating, by the image processing module, a depth map for the 2D view of the video presentation based on the global motion-adjusted optical flow.
