dc.description.abstract |
Image-based modeling can simplify the scene modeling process in
computer graphics by assuming that it is not the geometry of a scene
that is of interest, but rather the look of a scene. Instead of obtaining
detailed surface geometry and colour data, visual data alone is
acquired. This can be done with relative ease through photography.
Light Fields are a recent development in how such information is
stored. Images of a scene are used to create a four dimensional radiance
function. A light field determines what a scene looks like when
viewed from anywhere outside of the space enclosing the scene.
With light fields, as in many other image-based modeling and
rendering systems, there is a trade-off between quality and memory.
A high quality result requires storage of a large number of
samples obtained from high-resolution input images. The number
of images required can be reduced by using image warping techniques
based on image flow. Image warping computes intermediate
images from the existing images in the system, thereby giving the
illusion of a higher sampling density than that actually used during
acquisition. In this paper, we show how to use image flow in light
fields to produce high quality output from only a small set of input
images. Unlike previous work, we do not generate intermediate
images, but rather use image flow to render a new view directly.
High quality new views can be generated from as few as 8x8
images. We demonstrate several rendering methods for image-flow
augmented light fields |
