abstract = "Many applications, such as telepresence, virtual reality,
and interactive walkthroughs, require a threedimensional
(3D) model of real-world environments.
Methods, such as lightfields, geometric reconstruction
and computer vision use cameras to acquire visual
samples of the environment and construct a model.
Unfortunately, obtaining models of real-world locations
is a challenging task. In particular, important environments
are often actively in use, containing moving
objects, such as people entering and leaving the
scene. The methods previously listed have difficulty
in capturing the color and structure of the environment
while in the presence of moving and temporary occluders.
We describe a class of cameras called lag
cameras. The main concept is to generalize a camera
to take samples over space and time. Such a camera,
can easily and interactively detect moving objects
while continuously moving through the environment.
Moreover, since both the lag camera and occluder are
moving, the scene behind the occluder is captured by
the lag camera even from viewpoints where the occluder
lies in between the lag camera and the hidden
scene. We demonstrate an implementation of a lag
camera, complete with analysis and captured environ-
ments."
