Method and apparatus for processing 3-D multiple view images formed of a group of images obtained by viewing a 3-D object from a plurality of positions
First Claim
1. A method of processing 3-D multiple-view images comprising:
- acquiring by an image acquisition means, 3-D multiple-view images comprised of a group of images obtained by viewing a 3-D object from a plurality of viewpoints;
finding by an image analysis means, layered feature trajectory information connecting identical points of the 3-D object between images of the 3-D multiple-view images obtained by the image acquisition means; and
finding by interpolation by an image interpolation means, an image of the 3-D object viewed from any arbitrary viewpoint based on the layered feature trajectory information.

Abstract
A system for processing 3-D multiple-view images which can render an image of a 3-D object as seen from any arbitrary viewpoint based on the 3-D multiple-view images, provided with an image acquisition unit for acquiring 3-D multiple-view images of a 3-D object as seen from a plurality of viewpoints, an image analysis unit for analyzing 3-D multiple-view images comprised of a plurality of images and finding the layered feature trajectory information comprised of trajectories linking identical points of the 3-D object, an image interpolation unit for rendering by interpolation an image of the 3-D object as seen from a specified (by user) viewpoint based on the layered feature trajectory information, an image compression unit for approximating the shape and color and texture information for the individual trajectories of the layered feature trajectory information for compression coding, a memory unit for storing the coded layered feature trajectory information, and an image reconstruction unit for reconstructing the coded layered feature trajectory information read from the memory unit to the original layered feature trajectory information and applying it to the image interpolation unit.
