| Abstract: |
The present system and apparatus uses image processing to recognize objects within a scene. The system includes an illumination source for illuminating the scene. By controlling the illumination source, an image processing system can take a first digitize image of the scene with the object illuminated a higher level and a second digitized image with the object illuminated at a lower level. Using an algorithm, the object(s) image is segmented from a background image of the scene by a comparison of the two digitized images taken. A processed image (that can be used to characterize features) of the object(s) is then compared to stored reference images. The object is recognized when a match occurs. The system can recognize objects independent of size and number and can be trained to recognize objects that is was not originally programmed to recognize.

First Claim:

We claim:
1. A system for recognizing objects comprising:
- a. a light source for illuminating one or more of the objects, the illuminated objects being a target object, the light source having a non-monochromatic light frequency distribution that is constant over a period of time;
- b. a computer system having a visual input device for creating one or more scene images, the scene images capable of including a target object image of the target object and a background image, and the computer system further having a memory storage;
- c. a segmenter executing on the computer system that produces a segmented target object image by segmenting the target object image from background image by comparing a first scene image with a second scene image, the first and second scene images being in spatial registration and one or more respective positions in the first and second scene images having a difference being identified as the target object image;
- d. a plurality of reference normalized characterizations, each reference normalized characterization being of a feature associated with a segmented reference object, the reference normalized characterizations being stored in the computer memory storage; and
- e. a normalizer executing on the computer system that produces one or more target normalized characterizations, each target normalized characterization being of a feature of the segmented target object image,
whereby one or more of the target normalized characterizations, is compared with one or more reference normalized characterizations and the target object is recognized as the associated reference object if the compared target normalized characterizations and reference normalized characterizations match.
