Abstract:
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.
