Here
are number of screen captures demonstrating some of the capabilities
of the Holographic Video Player. Automatic depth perception is a
very ambitious task. Once the software understands the geometric
structure of the scene, while still in real time, it renders a wireframe
and continuously updates this as the video changes. Then, you can
navigate around objects as the video plays.
This
all happens using ordinary video, and even historic film footage.
There is no manual intervention to mark out the foreground objects,
no tracking markers, and no special hardware like laser range finders
or stereoscopic cameras. It works with all of the standard digital
video formats, and home users can render and navigate on ordinary
home PCs. This is designed to be a robust consumer product for home
entertainment. It is like having a 3D camera that saves the physical
scene structure along with each two-dimensional image.
In
each of the clips below, you'll see Dr. Craig Summers testing a
variety of different capabilities of the Holographic Video Player.
You can
view each of the following avi movie files with Windows Media Player
or Quicktime, as you prefer. Note that the file sizes are between
2 and 11 megabytes (mb), and will require at least a few seconds
to download.

Embossed
video
(5.7 mb): The most seamless approach to Holographic Video is
to keep the foreground objects attached to the background. The
scene is paused in this clip, to allow an inspection in 3D.
This was created automatically by the software, with no human
intervention. Compare the photorealistic quality of the the
head model to the primitive characters that are currently state
of the art in 3D console games. |

Background
Fill-In (2.8 mb): One of the powerful capabilities of the
software is the background that it generates. By buffering occluded
areas as foreground objects move, a complete representation
of the background is created. So when you navigate around in
the scene, you can look behind objects. In this experimental
version of the player, we have left the right window visible,
so that you can see yourself disappear in the foreground. |

Foreground
separation (4.2 mb): There is a control in the Player that
gives you the option to separate foreground objects from the
background. In this real-time example, the viewpoint is changed
while the video is running. The 3D rendering happens in real
time. Note that when viewed in perspective, you can see occluded
background objects. There is no empty space on the wall where
Dr. Summers is blocking the camera's view! The window on the
right shows the background that the software has created for
the scene model. |

Binocular
displays
(3.4 mb): Few head-mounted display goggles have stereoscopic
content that displays different perspectives to each eye, because
of the costs of production with special stereoscopic cameras.
Our software solves this problem by generating left-eye and
right-eye views in real time from ordinary video. Why use a
binocular display if you are not going to have different views
for each eye? This gives you pop-out like in the traditional
Disney Viewmaster -- except now it is with running video, processed
in real-time, that you can navigate in 3D! |

Grand
finale
(11 mb): Watch in this example as we render red and green channels
in real time for left and right-eye perspectives with anaglyph
3D glasses. Note that on the right, the scene model is shown
with the foreground person removed. So when the 3D scene is
viewed in perspective, there are no holes behind occluding objects.
3D navigation in moving video from an ordinary movie, that you
can watch with stereoscopic pop-out. |
