First Claim
Patent Images
1. Automated, computerized method for tracking an object in a motion sequence of images, comprising the steps of:
- a computer executing the following steps;
determining motion pixels from the motion sequence of images;
calculating Nth order tokens as a function of the motion pixels; and
identifying motion of an object as a function of the Nth order tokens, based upon a comparison of spectral ratios and reflectance ratios between Nth order tokens of separate instances of motion pixels, in separate images of the motion sequence of images.

Abstract
In an exemplary embodiment of the present invention, an automated, computerized method is provided for classifying pixel values in a motion sequence of images. According to a feature of the present invention, the method comprises the steps of determining spectral information relevant to the sequence of images, and utilizing the spectral information to classify a pixel as one of background, shadow and object.
