Appeal No. 2000-1179
Application No. 08/923,436
BACKGROUND
The invention is directed to a system for tracking and identifying view-based
representations of an object through a sequence of images. Claim 1 is reproduced
below.
1. An apparatus for identifying and tracking an object recorded in a
sequence of images, comprising:
a memory for recording a set of training images; the images in the set of
training images recording different views of the object;
means for generating a set of basis images corresponding to the set of
training images recorded in said memory; the set of basis images characterizing
variations of the views of the object in the set of training images; and
means for evaluating each image in the sequence of images to identify
changes in view and structure of the object while tracking the object through the
sequence of images with tracking parameters and identification coefficients; said
evaluating means incrementally refining the tracking parameters and the
identification coefficients by aligning, matching, and reconstructing a view of the
object in the image with the views of the object represented in the set of basis
images.
